Investigation of Boundary Conditions on the Conduction-Radiation Heat Transfer Analysis in Participating Media

The present paper is an effort towards the numerical simulation of coupled conductive and radiative heat transfer in presence of absorbing, emitting, and scattering gray participating medium within two-dimensional square enclosure. The walls of the enclosure are considered to be opaque, diffuse, and gray. The walls are subjected to different boundary conditions like uniform heating, linear heating and non-uniform heating. The discrete ordinates method (DOM) has been employed for modeling the radiative transport equation and the finite volume method (FVM) has been adopted as the numerical technique to solve overall energy equation (EE). The effect of various parameters, i.e., radiation-conduction parameter, wall emissivity, single scattering albedo, and optical thickness has been illustrated on the isotherm profile for the square enclosure.
