COMBINED CONDUCTION AND RADIATION IN A TWO-DIMENSIONAL RECTANGULAR ENCLOSURE

Abstract
The steady-state combined conduction and radiation heat transfer for an absorbing, emitting, and isotropically scattering two-dimensional rectangular enclosure is investigated. The boundary surfaces art considered to be black and subjected to a constant temperature on one surface and to zero temperature on others. The Galerkin method is used to obtain an exact solution to the radiation part of the problem, and a finite-difference scheme is applied to solve the conduction part. The effects of the conduction-to-radiation parameter, the single scattering albedo, and the aspect ratio on the temperature distribution are examined.
