Abstract
In this work, MHD mixed convection flow and heat transfer in an inclined lid driven enclosure with different angles (φ=0o to 90o) for two cases has been studied numerically. Simulations are carried out over a range of parameters: Prandtl numbers (Pr=0.7 and 7.2), Hartmann number(0≤Ha≤100), Richardson number (Ri=0.01,1.0,100) and Reynolds number (Re=100). The governing equations are solved by the finite volume method with a SIMPLE algorithm. It has been found that the average Nusselt number decreases with increasing Hartmann number. It is concluded that on increasing the Richardson number, the overall heat transfer is increased. Also, it is found that existence of the magnetic field suppresses the convective heat transfer and fluid flow in enclosure.
