Abstract
Consideration is given to the radiant interchange in a specularly reflecting circular-cylindrical cavity that is irradiated by an obliquely inclined beam of parallel rays passing through the cavity opening. A method of analysis is devised whereby the absorption of radiant energy can be determined without keeping track of individual rays as they undergo successive specular reflections at the curved wall of the cavity. Results are obtained both for the over-all energy absorption in the cavity and for the surface distribution of the locally absorbed radiant energy.
