✦ Synopsis

The transfer of energy between concentric cylinders has been considered, using a first order slip boundary condition. Results compare favourably with previously obtained numerical resuIts.

The study of thermal radiation is made difficult by the basic non-localized character of the phenomena. In addition, many real problems require the incorporation of the temperature and spectral variation of system properties. See, for example, Howell and Perlmutterl), Viskanta and Grosh2), and Cessa).
