چکیده
In the current work, two-dimensional simulations are presented for incompressible
laminar mixed convection flow of a radiating gas over a recess including two backward and
forward facing steps in a vertical duct. The continuity, momentum and energy equations for fluid
flow are solved by the computational fluid dynamic (CFD) techniques. The fluid is treated as a
gray, absorbing, emitting and scattering medium. For computation of the radiative term in the
energy equation, the radiative transfer equation (RTE) is solved numerically by the discrete
ordinates method (DOM). The effects of Grashof number, radiation-conduction parameter and
optical thickness on heat transfer behavior of the system are studied.
