Abstract
Convective flow and heat transfer between vertical wavy wall and a parallel flat wall consisting of two regions, one filled with electrically conducting and other with viscous fluid is analyzed. Governing equation of motion have been solved by linearization technique. Results are presented for various parameters such as Hartmann number, Grashof number, viscosity ratio, width ratio, conductivity ratio and source or sink. The effect of all the parameters except the Hartmann number and source or sink remains same for two viscous immiscible fluids. The effect of Hartmann number is to decrease the velocity at the wavy and flat wall. The suppression near the flat wall compared to wavy wall is insignificant. The velocity is large for source compared to sink for equal and different wall temperature.
