On the exact solution of a generalized equation of radiative transfer in atwo-region inhomogeneous slab

The problem of radiative transfer in a two-region inhomogeneous slab of equ al or unequal thickness has been solved with general boundary conditions. A Galerkin-iterative technique is used to solve the coupled integral equatio ns for the two-regions. Numerical results are obtained for the reflection a nd the transmission coefficients for the homogeneous and inhomogeneous case s. The results obtained for homogeneous medium are compared well with the e xact results. (C) 2000 Elsevier Science Ltd. All rights reserved.
