Abstract

The effects of thermal radiation upon the laminar flow of an absorbing, emitting, scattering gray fluid over an adiabatic flat plate are investigated. The combined radiation and forced convection in the boundary layer leads to a set of partial and integro-differential equations. In this work, three governing equations are setting as partial differential equations. A finite difference scheme is used to transform the resulting equations into an ordinary differential equation system which is solved numerically. Results for the temperature profiles across the boundary layer and the recovery factor along the flat plate are presented. Comparison of these results with exact solutions shows that the two flux model is simpler and accurate enough to treat the interaction of the thermal radiation with the laminar boundary layer.
