transfer characteristics in a wavy enclosure is presented. The control volume-based fi nite element method (CVFEM) has been adopted to solve numerically the governing conservation equations of mass, momentum, and energy by using a stream function vorticity formulation. Special att ention is given to understand the eff ect of a transverse magnetic fi eld on the heat transfer rate as well as fl ow confi gurations with diff erent amplitudes of sinusoidal wall. The numerical procedure in this analysis yields consistent performance over a wide range of parameters; Hartmann number, Ha; Rayleigh number, Ra; dimensionless amplitude of sinusoidal wall, a, and a fi xed Prandtl number (Pr = 0.025) for liquid metal. The results obtained are depicted in terms of streamlines and isotherms which show the signifi cant eff ects of the Hartmann number on the fl uid fl ow and temperature distribution inside the enclosure. It was found that the Nusselt number decreases with increase in the Hartmann number.
