In this paper, the effects of radiation (Rosseland model) on the flow of an incompressible fluid over a vertical flat sheet near the stagnation point with internal heat absorption or generation is studied. The similarity variables are used to transform the problem under consideration into a boundary value problem of nonlinear coupled ordinary differential equations containing the Prandtl number and heat source/sink parameter, which are solved, numerically by using the finite-difference method with appropriate boundary conditions. Numerical results are given for various values of dimensionless parameters of the problem. A comparison of numerical results is made with the earlier published results under the limiting cases. The effects of physical parameters on temperature and the local Nusselt number are discussed in detail. The results show that increasing the internal heat generation/absorption parameter increases the thermal boundary layer thickness and similar effects are seen for increasing the radiation parameter and wall temperature.
