Multi layer Radiation Solution for Boundary-Layer Flow of Gray Gases

The multilayer radiation solution technique is applied to the combined radiation-convection problem of a laminar boundary-layer flow of gray absorbing-emitting gases over a flat plate. The developing boundary-layer temperature profiles, boundary-layer thickness, and heat transfer from the plate are presented as functions of the temperature boundary conditions and radiation strength parameter. Radiation is seen to significantly enhance the heat transfer from the plate, and it alters the shape of the temperature profiles as it increases the boundary-layer thickness. The current boundary-layer solutions are in good comparison with the previously published results by Cess. The accuracy of the radiation solution is also separately considered for layers of known temperatures.
