Abstract
In this article, an alternative form of Tan's formulation was developed to describe thermal radiation problems in a gray, absorbing, emitting and isotropic scattering medium bounded by a gray and diffusely emitting and reflecting enclosure. The radiosity algorithm was adopted in the governing equations. A modified boundary element method was developed to solve the equations. A group of cases was studied. Numerical results agree well with data available in the literature which were obtained using other numerical algorithms. The modified boundary element method was found to be effective and accurate in treating general thermal radiation problems. Application of the boundary element method in solving thermal radiation problems is discussed.
