	abstract = {<p>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 \&lt;= Ha \&lt;= 100) and nanoparticles volume fraction (0 \&lt;= phi(0) \&lt;= 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.</p>},

	abstract = {<p>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.</p>},
