Abstract : This study examines the problem of an MHD free convection flow in the presence of a temperature-dependent heat source in a viscous incompressible fluid between a long vertical wavy wall and a parallel flat wall with constant heat flux and slip flow boundary condition, A uniform magnetic field is assumed to be applied perpendicular to the walls. It is assumed that the flow consists of two parts; a mean part and a perturbed part. Expressions for the zeroth-order and first-order velocity, temperature, skin friction, and Nusselt number at the walls are obtained. The effects of different parameters entering into the problem, viz., free convection parameter, magnetic parameter, and heat source parameter on the zeroth-order and first-order velocity fields, temperature field, skin friction, and Nusselt number at the walls are shown graphically and discussed numerically.
