Convection – Radiation Interaction In Buoyancy-Induced Channel Flow

The interaction of convection with radiation in buoyancy-induced flow in a corrugated channel is examined in the presence of heat source or sink. The walls of the channel are maintained at constant but different temperatures. The governing equations are solved by a perturbation technique and the resulting expressions are numerically evaluated. The effects of radiation parameter, wall-temperature ratio, heat source or sink parameter, and Prandtl number on the profiles of the total and first-order velocity and temperature functions are discussed and shown graphically.
