Abstract A finite-volume solution procedure for radiative heat transfer in a three-dimensional nonorthogonal enclosure containing participating medium is proposed with geometric relations commonly adopted in computational fluid dynamics. A general discretization equation is formulated by using the directional weight and the step scheme for spatial differencing. The present approach is validated through comparison with the problems of hexahedral enclosure, annular sector, and three-dimensional co

The conventional discrete-ordinates method is modified and developed for the analysis of two-dimensional axisymmetric cylindrical enclosure with absorbing, emitting, and either isotropiclly or anisotropically scattering gray medium. The main characteristic of the present method Is that the control angles can be arbitrarily specified pertaining to each problem dealt with. The scattering phase Junction is approximated by a finite series of Legendre polynomials. In order to validate the formulation
