Abstract
We report an investigation of radiative heat transfer in porous radiant burners. The combustion was modeled as a spatially-dependent heat generation. Using the spherical harmonics to solve the equation of transfer, we have obtained the P-1 and P-11 solutions for the irradiance and the net radiative heat flux. The accuracy of these solutions was assessed by comparing to an exact solution for uniform heat generation in the porous layer. Results presented illustrate the radiant output as a function of the position of the combustion zone, the optical thickness and the type of scattering of the porous layer, and the amount of reflection from the distribution chamber.
