Effect of volumetric absorption coefficient on Rosseland radiative heat transfer.

Expert InsightsPublished 1966

A clarification of some factors relating to the use of Rosseland's approximation for the radiative heat flux in calculating the temperature profile and heat transfer associated with an optically dense fluid. Although Rosseland's approximation lends itself to such calculations, since its form can be used in partial differential equations, very little is known about the form of the absorption coefficient which is the fluid-characteristic term in the approximation. The Paper shows that, in the case of uniform fluid (optically dense) flow past a flat plate, the calculated temperature profiles and heat transfer to the wall by radiation alone are very sensitive to the choice of the form of the absorption coefficient.

This publication is part of the RAND paper series. The paper series was a product of RAND from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
