RÉSUMÉ

The purpose of the present study is to numerically investigate mixed convection (both free and forced) together with thermal radiation heat transfer in a three-dimensional vertical square channel with consideration for all the radiative properties (absorbing, emitting, and scattering) for the participating medium and the walls. The flow in the channel is assumed to be laminar and steady. The temperatures of the opposite walls are considered to be different (i.e., asymmetrical heating). The 3D governing equations include continuity, momentum, energy, and radiation transfer equations (RTE). By solving them together, the velocity and temperature fields are determined. The SIMPLE algorithm with a staggered system is employed to solve the corresponding equations formulated by the finite-volume method and 3D discrete ordinates method, employing its S6 quadrature scheme. A fifth-order power-law scheme is used to model the convection term and a suitable grid distribution is introduced. The validity of the present results is checked against the available numerical data. The main objective of the present work is to evaluate the effects of radiation parameters such as conduction−radiation parameter and optical thickness on heat transfer and also on the occurrence of flow reversal in the channel. The results are presented as the velocity and temperature profiles displaying that the influence of these parameters on the flow is considerable.
