Effects of anisotropic scattering to heat transfer in hydrodynamically‐developed, thermally‐developing steady laminar forced flow of a gray fluid between two infinite parallel plates are investigated for the case when the inlet temperature of the fluid is less than the wall temperature. An implicit finite difference scheme is applied to solve the energy equation, while the high order P N method is used to solve the radiation part of this problem. The effects of the anisotropy, the conduction‐to‐radiation parameter, the optical thickness, the reflectivity of the plates and the inlet temperature on the local Nusselt number are studied.
