Radiative transfer in a twodimensional rectangular bar geometry with a specularly reflecting boundarysource function expansion solution
Abstract
The radiative heat transfer problem in an absorbing, emitting, and isotropically scattering twodimensional medium with emitting and reflecting boundaries is formulated in an integral equation for the source function. The medium is assumed to be nongray and nonisothermal with uniform radiative properties at a given frequency. The problem is then solved using the source function expansion method, which has been applied to similar problems in the slab geometry and to simpler problems in the twodimensional bar geometry. Results are presented for the component heat fluxes and for the source function for a range scattering albedo and specular reflectance. The method provides an accurate and computationally fast and accurate solution of spectral quantities.
