In the present work, a numerical solution is described for turbulent
forced convection flow of an absorbing, emitting, scattering and gray fluid
over a two-dimensional backward facing step in a horizontal duct. The AKN
low-Reynolds-number model is employed to predict turbulent flows with
separation and heat transfer, while the radiation part of the problem is
modeled by the discrete ordinate method (DOM). Discretized forms of the
governing equations for fluid flow are obtained by finite volume approach and
solved using SIMPLE algorithm. Results are presented for the distributions of
Nusselt numbers as a function of the controlling parameters like
radiation-conduction parameter (RC) and optical thickness.
