The aim of this study is to present a new hybrid solar-biomass dryer and carry out thermal analysis based on energy and exergo-sustainability analysis considering all the available exergy stream of solar radiation, air stream through the collector, and exergy of the moisture in the product. The research also presented the environmental impact and economic analysis of using the dryer. Performance evaluations show that at collector efficiency of 20.81\%-21.89 \%, the developed solar dryers can save between 10-21hrs of drying time in drying 5 mm thick plantain slices to 15 \% moisture content from initial moisture content of 66 \% w.b when compared to drying under the open sun. The improvement potential ranged from 0.036 to 20.6W while the waste exergy ratios and sustainability index ranged from 0.38-0.55 and 2.3-6.11 respectively. Application of the solar dryers can save between 44-3074 of CO2 entering the atmosphere per year while 2.94 to 205.43$ could also be saved at 10-100\% rate of usage when compared to diesel fired dryer. The total energy consumption for drying ranges between 5.52 and 35.47 MJ, while the specific energy consumption ranged from 4.3 to 26.2 kWh/kg. The exergy efficiency ranges from 5.6-95.13 \% during the sunshine hours.

This paper presents experimental and numerical investigations on the vibrational serviceability performance of novel adhesive free engineered wood products (AFEWPs), namely adhesive free laminated timber beams (AFLB) and adhesive free cross-laminated timber panels (AFCLT), assembled through thermo-mechanically compressed wood dowels (CWD). The laminations composing the AFEWPs are made of oak timber while the CWD are made of spruce. The experimental modal analyses were carried out under free-free conditions using a hammer impact. Natural frequencies, mode shapes, and damping ratios were assessed experimentally. In addition, similar glued beams made of oak timber (conventional glulam) were manufactured and tested for comparison purpose. A predictive 3D FE model was developed and validated by comparison against experimental data and then used to predict the vibrational behavior of a realistic flooring system made with AFCLT panel and measuring 4.5 m x 5.5 m. The predicted FE results were discussed with regard to the Eurocode 5 vibrational serviceability design requirements showing acceptable vibrational performance. The variability level of the results for the AFEWPs is also studied and discussed.

Drying is a simultaneous heat and mass transfer processes. Drying kinetics is determined by both internal properties and external drying conditions. In this study, two important drying kinetics parameters of onions i.e. effective water diffusivity and relative activation energy of reaction engineering approach (REA) are determined. The generated parameters are used to model thin layer drying of onion at different temperatures (40, 50, 60, and 70 degrees C) and relative humidity of 20\%. The effective water diffusivity is in the range of 2.8x10(-10)m(2)s(-1) and 8.1x10(-10)m(2)s(-1). Unlike the diffusivity, the relative activation energy of the REA is independent on drying conditions and thus the latter approach requires less effort in generating the transport properties. The transport parameters can be applied for assisting in designing dryer units and evaluating the performance of existing dryer units.

This paper presents an experimental investigation on a novel adhesive free engineered Wood Products (AFEWPs) as an alternative to the conventional glued EWPs which have a high degree of petrochemicals. The research outcomes demonstrate the feasibility of using compressed wood dowels (CWD) as a joint element, to connect timber laminates and members as well as to substitute for adhesives and metallic fasteners. The paper describes the production of thermo-mechanically compressed wood dowels as well as the manufacturing of the dowelled timber specimens. The strength and stiffness properties of CWD are characterized based on three-point bending tests and compared to the values obtained from uncompressed wood specimens. After that, the paper discusses the relative mechanical performances of three-layer dowelled oak beams subjected to four-point bending, in comparison to their conventional glued counterparts. Finally, the paper shows results obtained from double shear push-out tests under both monotonic and cyclic loadings, using two wood species, namely spruce and oak. The obtained results show clearly the potential of thermo-mechanically compressed wood dowel, as a joint fastener, for load bearing capacity.

The effect of extraction conditions on polyphenols contents and condensed tannins by microwave-assisted extraction (MAE) was studied for the first time to our knowledge. Moroccan barks of Acacia mollissima was used to extract phenolic compounds. The variables studied are the following: power extraction, time extraction and solvent nature. Five powers extraction were tested: 150 W, 250 W, 300 W, 450 W and 600 W. A significant effect of power extraction on the extractable nature was proved by ANOVA and Student test. The yields were also affected by time extraction. Different solvent (water, ethanol, methanol and ethyl acetate) were tested to evaluate the best extraction solvent according to the extractable nature. Highest polyphenols contents were obtained with methanol. The proportion of this solvent, time extraction and power extraction were optimized using the response surface methodology (RSM). A face-centered composite design (FCCD) was applied to evaluate the effects of these variables on the polyphenols and condensed tannins contents. For each experiment, the extraction yield, the total polyphenolic contents and the condensed tannins contents were quantified using colorimetric essays. The extracts were characterized by their reactivity to formaldehyde and reverse phase high pressure liquid chromatography (RP-HPLC). The highest polyphenols content was obtained at 156 W using 80\% of methanol during 5 min. For condensed tannins, the highest content of cyanidin was obtained at 182 W using 20\% of methanol during 3.66 min. RSM applied in MAE, permitted to develop green extraction process of polyphenols and tannins extracted, using lower microwave power and methanol proportion with a shortest time extraction and in the same time improve the quantity of extractables obtained from renewable natural resource.

Steam-explosion lignin (SEL) was extracted with ethanol from steam-exploded hardwood (okoume, Aucoumea klaineana Pierre) pretreated at various severities after neutral or acidic impregnation. The SELs were subjected to structural characterization by 2D HSQC NMR, P-31 NMR, and SEC and compared with milled-wood lignin (MWL). A strong decrease in the beta-O-4 content is observed with increasing steam-explosion severity accompanied by a gradual increase in molecular mass. C alpha-oxidized S units (S\&$\#$39;, Hibbert\&$\#$39;s ketones) were quantified by NMR and used as a marker of the hydrolytic mechanism; naphthol was used as a carbonium-ion scavenger. It has been observed that mixed reactions of hydrolysis and homolysis are involved, but the SEL is mainly cleaved homolytically, favoring recondensation through radical coupling even at low reaction severity. However, acidic preimpregnation of wood prior to steam explosion enhanced the carbonium-ion pathway.

Numerical study for the effect of an external magnetic field on the mixed convection of Al2O3-water Newtonian nanofluid in a right-angle vented trapezoidal cavity was performed using the finite volume method. The non-homogeneous Buongiorno model is applied for numerical description of the dynamic phenomena inside the cavity. The nanofluid, with low temperature and high concentration, enters the cavity through the upper open border, and is evacuated through opening placed at the right end of the bottom wall. The cavity is heated from the inclined wall, while the remainder walls are adiabatic and impermeable to both the base fluid and nanoparticles. After validation of the model, the analysis was carried out for a wide range of Hartmann number (0 \<= Ha \<= 100) and nanoparticles volume fraction (0 \<= phi(0) \<= 0.06). The flow behavior as well as the temperature and nanoparticles distribution shows a particular sensitivity to the variations of both the Hartmann number and the nanofluid concentration. The domination of conduction mechanism at high Hartmann numbers reflects the significant effect of Brownian diffusion which tends to uniform the distribution of nanoparticles in the domain. The average Nusselt number which increases with the nanoparticles addition, depends strongly on the Hartmann number. Finally, a correlation predicting the average Nusselt number within such geometry as a function of the considered parameters is proposed.

The present paper investigates numerically the effect of an external magnetic field on heat transfer and entropy generation of Ag-MgO (50:50vol\%)/water hybrid nanofluid flow in a partially heated irregular ventilated cavity. A finite-volume FORTRAN code has been written to solve the governing partial differential equations. New empirical correlations specifically dedicated to predict the dynamic viscosity and the thermal conductivity of the considered hybrid nanofluid were employed. After validation of model, the analysis has been done for a wide range of Reynolds number (10?Re?600), Hartmann number (0?Ha?80) and total nanoparticle volume fraction (0?phi?0.02). The results are presented in terms of streamlines, isotherms and isentropic lines as well as the average Nusselt number (Nu(m)), the average entropy generation (S-gen,(m)) and the Bejan number (Be-avg). The criterion =S-gen,(m)/Nu(m) is adopted to discuss the thermal performances of the system. The results reveal that the intensification of the magnetic field tends to attenuate the heat transfer convection and to reduce the thickness of the thermal boundary layer, close to the active walls. Globally, adding nanoparticles to the base fluid improves the heat transfer but increases the total entropy generation.

Cellular materials such as wood are widely and advantageously used as shock absorbers in various transport applications. The design and manufacturing of structures made of these materials require the knowledge of their dynamic compressive properties at various strain rates and stress states. Therefore, it is challenging to conduct dynamic multiaxial stress state experiments and especially on split-Hopkinson pressure bar apparatus where stress hardening increases as a function of velocity. This paper presents the so-called verification and validation methodology for confining solutions dedicated to impact on viscoelastic split-Hopkinson pressure bar system with large diameter bars. The method is a hybrid approach combining finite element analysis and an original experimental validation. Based on finite element results, particular attention is given to the mass, the material and the geometry to minimize the confining device influence on the propagation of elastic waves and thus on the material response of the tested specimens. It is essential to avoid spurious reflected waves at the new interfaces of the system in order to ensure the validity of the experimentation. The numerically predicted solutions are experimentally validated and preliminary results in the context of dynamic loadings using wood material are presented.

This work focuses on the development of a three dimensional constitutive model for timber to simulate the flexural behaviour of hybrid timber-steel and timber-concrete beams. This is motivated by the lack of dedicated non linear material behaviour laws for timber in the commercial finite element software by compared to the conventional materials such as concrete and steel.

The flexural behaviour of hybrid timber beams is very complex because of the combination of the two different material behaviours and their nonlinar and partial compostion action. Numerical simulation of such behaviour requires an accurate description of the nonlinear material behaviour, in particular that of timber because of its anisotropic nature. A realistic description of the material nonlinearities and of the composite action between the different materials could aid considerably in achieving acceptable predictions. An incremental approach based on the strong coupling between orthotropic elasticity, anisotropic plasticity with mixed nonlinear isotropic hardening and an isotropic damage is used. The developed constitutive model for timber is implemented in Abaqus code using an external subroutine. The 3D FE model is calibrated and validated through comparison with experimental data reported in literature. The model is able to predict the nonlinear structural response of hybrid beams in terms of load-midspan deflection, and provides an acceptable accuracy.

Fire design requires three fire resistance criteria, namely integrity, insulation and load-bearing. In particular, repartition wall systems used in residential and commercial buildings are required to provide certification of insulation and integrity fire resistance and have to be analysed in the context of the characteristic time scales of a fire. This paper presents a numerical methodology to simulate the fire integrity resistance of full-scale timber based wall systems exposed to fire. The main contribution of this paper, with regard to the existing literature, is the presence of cross-laminated timber (CLT) panel in the central part of the wall system, where the pyrolysis of timber was modelled explicitly in the energy balance equation system. For this end, a user-subroutine, called UMATHT, is developed and successfully implemented in the Abaqus finite element code for thermal analysis. The falling off of the gypsum boards under fire was considered implicitly in the FE model based on experimental observations. The obtained results show clearly the need to take into account explicitly the cracks and falling off of the gypsum boards for an appropriate prediction of the integrity fire resistance in order to reduce expensive experimental procedures.

Numerical simulation of reinforced concrete structures requires the explicit representation of both the concrete and the reinforcement bars, where the two materials are modelled separately using appropriate constitutive laws including damage variables for concrete in compression and tension. Even if this way of modelling is convenient and satisfactory, it requires a huge computational effort especially in the case of large scale applications. The aim of this paper is to develop an alternative model dedicated for the simulation of large scale reinforced concrete structures with no need to represent explicitly the steel reinforcements. Based on the literature review, the authors developed a fictitious stress-strain relationship for reinforced concrete under tension. The model is based on the shape of the slip-adhesion curve between steel and concrete proposed by the European Committee for Concrete (C.E.B.) to estimate the crack opening widths. Relationships covering the cracked stage up to the yield point of the steel are proposed depending on the material properties of concrete and steel, on the reinforcement ratio, as well as on the crack widths. The developed model was successfully implemented in the ABAQUS commercial software. The effectiveness and computational efficiency are demonstrated through some examples under tensile and bending loadings.

The compressive properties of spruce and beech wood species at a large range of strain rates - from 0.001 to 600 s(-1)- under rigid lateral confinement have been investigated, using an original experimental device especially developed for the purpose. The work is motivated by the need to explore the dynamic behavior of wood up to large strains close to 70\%. Three experimental apparatus have been used to obtain the compressive responses: the quasi-static tests have been performed using a Sintech 20D test system, the compressive responses at intermediate strain rates have been obtained with an Instron VHS65/20 apparatus and the dynamic tests have been conducted using a Split Hopkinson Pressure Bars (SHPB) system. The strain rate sensitivity of wood is clearly visible on the crushing strength with an increase between 80 and 155\% but also on the plastic like behavior. In addition, the entire responses exhibit an elastic-plastic like behavior whereas an elastic brittle behavior could be observed, in the previous Part A which was focused on the compression configuration without lateral confinement. Even if no significant effect of the rigid lateral confinement is observed on the apparent Young modulus and the crushing strength values for both species, the wood energy absorption capability is better when longitudinal failure mechanisms are restricted thanks to the rigid lateral confinement.

This study investigates the thermal energy potentials and economic feasibility of an air-conditioned family household-integrated phase change material (PCM) considering different climate zones in Morocco. A simulation-based optimisation was carried out in order to define the optimal design of a PCM-enhanced household envelope for thermal energy effectiveness and cost-effectiveness of predefined candidate solutions. The optimisation methodology is based on coupling Energyplus (R) as a dynamic simulation tool and GenOpt (R) as an optimisation tool. Considering the obtained optimum design strategies, a thermal energy and economic analysis are carried out to investigate PCMs integration feasibility in the Moroccan constructions. The results show that the PCM-integrated household envelope allows minimising the cooling/heating thermal energy demand vs. a reference household without PCM. While for the cost-effectiveness optimisation, it has been deduced that the economic feasibility is stilling insufficient under the actual PCM market conditions. The optimal design parameters results are also analysed.

Energy efficiency improvement in building sector has become a real challenge in Morocco, especially in the northern region evolving a rapid urban growth. In this context, using the phase change materials (PCM) in the construction is presented as one of the promising solutions to enhance the thermal behaviour of building envelope. This work aims to investigate the thermal performance of a PCM integrated external wall and roof under the summer climate conditions of northern Morocco. Dynamic thermal characterization methodology is adopted through the calculation of decrement factor (DF) and time lag (TL) parameters. For that, a one-dimensional numerical model based on resistance-capacitance (RC) approach is developed and implicitly solved to simulate the heat transfer process through a wall/roof structure. The model is validated through a new small-scale experimental device. Different qualities of PCM, regarding its peak phase change temperature, have been evaluated. Moreover, the PCM layer emplacement within the wall/roof structure was evaluated considering two possible configurations. The obtained results show a significative enhancement of the thermal performance of different wall facades and roof through the use of the suitable PCM quality. An appropriate selection of PCM layer emplacement yields an evidenced enhancement in the case of the roof. As for the walls, the integration of PCM from the interior side increase the TL period but has a negative impact on the DF parameter.

Natural convection, in a shallow horizontal cavity filled with a nanofluid, is studied. The flow is driven by Lid driven convection (LDC). External applied constant heat fluxes on the bottom wall of the cavity is applied, whereas the vertical walls are subjected to variable heat fluxes. The nanofluid concentration is treated as heterogeneous mixtures with a weak solutal diffusivity. A modified formulation taking into account the physical properties (thermal conductivity, viscosity) versus on nanofluids type and concentration and the spatial heterogeneous concentration induced by the Soret effect is presented. The induced nanofluid heterogeneity can affect the heat transfer. The heat transfer increases with increase of the boundary motion. The analytical solution, based on parallel flow approximation, is found to be in good agreement with numerical solution. The existence of both natural and anti-natural flows is demonstrated. Indeed, the subcritical Rayleigh number for the onset of instability tends to disappear when the supercritical threshold is largely affected.

Both monotonic and cyclic performances of joints have been evaluated and compared to the corresponding values calculated based on the Eurocode 5. The obtained results show clearly the potential interest and performances of hardwood structural joints for high load bearing capacity, as compared to their equivalent softwood joints. The obtained results showed also that the predictions of the European Yield Model regarding the load-carrying capacity penalize the joints made of hardwood species.

Since timber is a combustible material, its safe use in construction will depend on a proper knowledge and modelling of the physical and chemical reactions involved in the pyrolysis, that affect the temperature growth and thus the performance of timber in fire. Based on the comprehensive one-dimensional analytical models of the pyrolysis available in the literature, it is required to implement a predictive FE model via a user-defined subroutine in the dedicated commercial software in order to describe more closely the real physical phenomena that undergo timber exposed to fire. This paper presents the implementation of the UMATHT subroutine in the Abaqus software. The obtained results showed a fairly good agreement with experimental ones from the literature. However, at this stage of the study the pyrolysis is taken into account implicitly in the developed UMATHT through gradually modified thermo-physical properties of the timber, as commonly adopted in the published literature. Work is now in progress to implement explicitly the different reactions of the pyrolysis in the developed UMATHT.

The aim of this paper was to determine the moisture desorption isotherms and essentials thermodynamic properties of two Oak wood varieties. Desorption isotherms were measured using a static gravimetric method at 50, 60, 70 and 80 degrees C within the range of 5-90 \% relative humidity. The equilibrium moisture content decreased with increasing temperature and decreased with decreasing relative humidity at a constant temperature.

The Fiber saturation point, deduced from the \&$\#$39;Thermodynamic\&$\#$39; model parameters, depends on the temperature and varying from 22.6 to 54.4 (\% kg water/kg dry matter).

The isosteric heat of desorption and the differential entropy decreased with increasing moisture content according to an exponential law equation and varying from 2.03 to 31.14 kJ/mol and from 73.98 to 4.34 J/(mol K), respectively. The linear relationship between differential enthalpy and entropy satisfied the enthalpy-entropy compensation theory. The sign of Gibbs free energy was found to be positive (+283 J/mol) and (+97 J/mol) for Quercus robur and Quercus canariensis, respectively. The isokinetic temperature was found to be greater than the harmonic temperature. Based on the enthalpy-entropy compensation theory, it could be concluded that the moisture desorption isotherm of Oak wood is a non-spontaneous and enthalpy-controlled process.

Optimal linear wood welding parameters along the end-grain-to-end-grain faces were determined for Eucalyptus saligna, Eucalyptus pilularis, and Corymbia maculata. Joints made using Eucalyptus saligna showed a significant interaction between welding time ( WT), amplitude ( WA), and pressure ( WP). A preheating phase of 3 s at 0.4 MPa WP and 0.75 mm WA coupled with a WT of 2 s at 2.0 MPa WP and 1.5 mm WA provided the best shear strength results of 5.1 MPa. Joints made using Eucalyptus pilularis and Corymbia maculata snapped once the holding pressure was removed, suggesting that end-grain-to-end-grain welded fibers cannot withstand the thermal stresses generated when the surface to be welded is too small ( e. g., 13.5 cm(2)). However, grain orientation had a significant effect on the weld mechanical properties, as very strong edge-grain-to-edge-grain joints were produced with Eucalyptus pilularis and Corymbia maculata ( 9.5 and 6.2 MPa, respectively). The joints made of Eucalyptus saligna also showed significant improvement ( 7.3 MPa). Energy efficient combinations were usually those involving low WA and short WT, as WP had a marginal effect on energy consumption during the welding process.

Experimental and finite element (FE) studies of bending behaviour of finger-jointed timber (Spruce) beams reinforced with CFRP material were performed. Four-point bending tests with distinct reinforcement configurations were proposed in order to determine stiffness, ductility and strength values of strengthened finger-jointed timber beams. The experimental results obtained under flexure showed that the external bonding of CFRP increased the load-bearing capacity of finger-jointed Spruce timber beams. The numerical results presented here were based on the Cohesive Zone Model (CZM) available in Abaqus code, allowing the description of the progressive failure mode of the finger-jointed timber beams under flexural load. The FE models took the different material constitutive laws (wood, CFRP and adhesive) into account, including the bond-slip actions between finger-joints and CFRP-timber interface. The results in terms of load-mid span deflection and failure modes obtained experimentally and numerically were compared. Once the FE simulations were calibrated, the differences between experimental and predicted ultimate loads were around 4.5\% only. A good agreement was therefore found, proving the relevance of the presented FE models to predict the load-bearing capacity and to capture the failure mode of CFRP-strengthened finger-jointed Spruce timber beams in bending.

This paper presents an experimental investigation on full-scale glued solid timer beams made of oak timber, for structural purposes. Similar experimental work was previously presented by the authors using beech timber (Tran et al., 2012). Here, the results from the previous work were served for comparison purpose between the performances of the two hardwood species (oak and beech). The obtained results showed that the glued solid timber beams made of oak timber perform relatively more much better than their counterparts made of beech timber, which was explained by the weakness in the finger-joint due to a poor adhesion within the beech timber.

Non-Fickian diffusion in native and thermally modified wood was analyzed by the inverse method. A low quality of the identified diffusivity values was found for the diffusivity which was either constant or varying with water content. This was explained by the non-Fickian behavior. It was especially distinct for thermally modified wood for which an increased delay in obtaining the hygroscopic equilibrium was clearly shown. Such a delay was explained by time required for molecular reorganization to produce new sorption sites. This phenomenon was accounted to improve the physical model by modifying the convective boundary condition. A relaxation mechanism was used for this purpose with an adequate time constant.

Strain rate effect on wood material is of major interest when dealing with applications dedicated to energy absorption or wood machining. To understand and evaluate the strain rate influence on the wood responses, three experimental apparatus are used in order to cover a large range of strain rates, between 0.001 and 600 s(-1), and to allow observing densification regime for strains until 70\%. The influence of strain rate on mechanical properties, in particular, initial crushing stress, plateau stress and specific absorbed energies is investigated in the three orthotropic directions for two wood species (spruce and beech) really different in terms of relative density and microstructure. It is noticed that wood properties are strain rate sensitive and this sensitivity depends on the loading direction.

Natural convection, in a shallow horizontal cavity filled with two layers immiscible fluids, is studied both numeric and analytic. The horizontal walls of the enclosure are heated by the bottom and cooled by the upper by a uniform heat fluxes while the verticals one are subject to heat fluxes of variable intensity. The analytical solution, based on the parallel flow approximation, is found to be in good agreement with a numerical solution. The existence of both natural and antinatural flows is demonstrated. Indeed, the critical Rayleigh number for the onset of motion is dependent on the side heating intensity. In the case where the upper fluid is more viscous than the bottom one, multiple solutions are possible as well as the a steady states in a range of ratio of the viscosity of the fluids. The fact that one of the two fluids is more heat conductive, affect not only heat transfer generated but also the intensity of flows and the existence of the third cell where we found several solutions. The present model yields explicitly the flow patterns and Nusselt numbers in terms of the governing parameters of the problem.

The performance of three techniques, conventional maceration at room temperature, infusion and microwave assisted extraction, was evaluated to extract polyphenols, condensed and hydrolysable tannins from Moroccan barks of Acacia mollissima. A comparison of these methods was performed using colorimetric assays. For each technique, the effect of extraction conditions on the yield extracts was evaluated. The variables studied are: solvent nature, barks ages, time extraction, power extraction and heat interaction with solvent nature and barks ages. This study proved that the choice of solvent extraction was a relation of the extraction method used and the extractible nature (polyphenols, condensed or hydrolysable tannins). Methanol was the best solvent to extract tannin and polyphenols using maceration at room temperature, and ethanol was the best for infusion at 60 degrees C. Microwave was more selective to extract polyphenols and tannins under extraction solvent used. Highest polyphenols contents was obtained using methanol. For condensed and hydrolysable tannins, the highest were obtained using water. The polyphenols contents extracted using maceration was closed to the yield obtained with microwave, 354 mg GAE/g bark, 442 mg GAE/g bark, respectively. This study proved the pertinence of traditional methods to extract polyphenols and tannins compared to the new extraction method (microwave). The best polyphenols yields, condensed and hydrolysable tannins were obtained by microwave followed by the yield obtained by maceration and finally the yield obtained by infusion.

This paper deals with simulation of the spreading and solidification of a fully molten particle impacting onto a preheated substrate under traditional plasma spraying conditions. The multiphase problem governing equations of mass, momentum and energy conservation taking into account heat transfer by conduction, convection, and phase change are solved by using a finite element approach. The interface between molten particle and surrounding air, is tracked using the Level Set method. The effect of the Reynolds number on the droplet spreading and solidification, using a wide range of impact velocities (40-250 m/s), is reported. A new correlation that predicts the final spread factor of splat as a function of Reynolds number is obtained. Thermal contact resistance, viscous dissipation, wettability and surface tension forces effects are taken into account.
