Approximate Solution to the Radiative Equilibrium Between Concentric Spheres

Abstract

An approximate method was developed for the study of the radiative energy transfer through a gray gas layer enclosed between black concentric spheres which are maintained at uniform but different temperatures. The basic concept consists of assuming a temperature distribution through the gas layer, and assigning appropriate jump boundary conditions to evaluate the flux distribution using the exact integral equation governing the flux for this geometry. The approximate solutions have been found to agree very well (6 per cent maximum deviation) with the existing exact numerical solution throughout the entire range of optical thickness. © 1972.
