Radiative Transfer From a Gray, Absorbing-Emitting, Isothermal Medium in a Conical EnclosureSource: Journal of Solar Energy Engineering:;1989:;volume( 111 ):;issue: 004::page 324Author:Deborah A. Kaminski

Abstract: Radiative heat transfer from an isothermal participating medium in a truncated, conical enclosure is investigated numerically. Two methods of solution are employed: the Monte-Carlo technique and the P 1 differential approximation. The solution to the P 1 representation is obtained from a control-volume-based discretization of the governing equation. The medium is assumed to be gray and nonscattering, and the absorption coefficient and temperature are uniform throughout the medium. Overall and local heat flux rates at the walls predicted by the P 1 method are compared to the quasi-exact results of the Monte-Carlo solution. Results are obtained for a variety of optical thicknesses and cone shapes.
