Abstract :
We determine the effect of radiation on the forced convection flow of an optically dense incompressible fluid along a heated horizontal stretching surface. The boundary-layer equations are transformed to ordinary differential equations containing a radiation parameter R*, velocity exponent parameter M, Prandtl number Pr, and surface temperature parameter teta. The effect of these parameters are studied. Graphical results for the velocity and temperature Aare presented and discussed.
