Abstract:

The radiant heat transfer from a spherically symmetric medium to an interior spherical boundary is considered. The medium is assumed to be gray with a constant absorption coefficient. Solutions are presented in terms of an emission function which may depend arbitrarily on the radial co-ordinate. The exact solution is obtained and compared with the known planar slab approximation. The differential approximation and a new extension of the differential approximation, in which only body orientated radiation is considered, are also applied to the same problem. Numerical values are obtained for emission functions having a power law dependence on distance from the inner boundary. Author
