The left and the right side walls of the cavity are maintained at temperatures Th and Tc, respectively, with Th > Tc. The enclosure's top and bott om walls are adiabatic. The transport equations are discretized using the finite volume method. Comparisons with previous works are presented and found to be in excellent agreement. The heat and fluid flow structures are fully investigated via streamlines and isotherms. A parametric study is carried out and the effects of the Rayleigh number, Hartmann number, and Joule heating on the fluid flow and heat transfer inside an enclosure are studied. The results show that the average Nusselt number increases with the Rayleigh number. Finally, it is found that a magnetic field has strong influence on the rate of heat transfer while the role of the Joule heating is marginal.
