A MODEL COMBUSTOR HEAT TRANSFER PROBLEM Radiative Transfer Between Surfaces with Nongray Gases and Soot
Abstract
The effect of temperature profiles of gases, concentration profile of species, surface reflectivity and specularity of surfaces on the wall heat flux is investigated for a parallel plate geometry enclosure. The Mayer-Goody band model in conjunction with a modified Curtis-Godson approximation to account for the inhomogeneous path, and the just overlapping line model, are employed for integration of the radiation transport equation. Three absorbing-emitting species, H2O, CO2 and carbon particles (soot), mixed with air are considered. Non-gray calculations are performed with 25 cm-1 spectral resolution using mostly experimental data. Some typical results and detailed conclusions are presented.
