Radiation Effects Upon Boundary-Layer Flow of an Absorbing Gas

Abstract

An analysis has been made to determine the effect of thermal radiation upon heat transfer to boundary-layer flow of an absorbing gas. Laminar flow across an isothermal flat plate is considered, and first-order interaction effects between the convection and radiation processes are evaluated for a gas with Pr = 1.0. The plate surface is assumed to be gray, and two types of gases are considered: a gray gas and a nongray gas for which the monochromatic absorption coefficient is assumed to be independent of temperature. The first-order results for the simplified version of a nongray gas differ substantially from those for the gray gas.
