Abstract : In calculating the temperature profile and heat transfer associated with an optically dense fluid it has been the practice to use Rosseland's approximation for the radiative heat flux, since its form lends itself well for use in partial differential equations. However, very little is known about the form of the absorption coefficient which is the fluid-characteristic term in the approximation. It is revealed in the analysis that in the case of uniform fluid (optically dense) flow past a flat plate, the calculated temperature profiles and heat transfer to the wall by radiation alone are sensitive to the choice of the form of the absorption coefficient.
