Effects of Conduction on Magneto-Hydrodynamics Mixed Convection Flow in Triangular Enclosures

Abstract

We study the significance of conduction with magneto-hydrodynamics (MHD) mixed convection flow in triangular enclosures. The enclosures consist of one temperature of the left moving wall, which has constant flow speed. A uniform magnetic field is applied in the horizontal direction normal to the moving wall. The results indicate that both the flow and the thermal fields strongly depend on the Hartmann number Ha, Prandlt number Pr for fixed Reynolds number Re, at the convective regimes. It is also observed that, the parameters Prandtl number Pr influence on the flow fields and have significant effect on the thermal fields at the convective regimes. According to the results it is found that both the flow and thermal fields inside the enclosures strongly depend on the relevant dimensionless groups. For the purpose of comparison of the effect of MHD on heat transfer, the results in terms of average Nusselt number and average temperature are shown in tabular form.
