Abstract

Combined thermal radiation and conduction in two-dimensional emitting, absorbing and anisotropic scattering square media is studied by solving numerically the exact integral and differential equations. The product integration method is applied for discretizing the radiative transport equations of integral form. For comparison, the zonal method is also used for radiation in some cases. In solving the resulting nonlinear equations, Chen's method is applied and improved. Comparison shows excellent agreement between the results given by the product integration method and the zonal method. The improved Chen's method is found to be efficient. Influences of various radiation-conduction parameter, optical thickness, scattering parameters and wall emissivity on heat transfer and temperature distribution are discussed.
