Radiation transfer in inhomogeneous media

The emergent flux for radiation transfer in an inhomogeneous half-space for both linear and generalized exponential c(x) is obtained by using both mod ified-Eddington method and P-1 approximation. Our choice for the generalize d exponential c(x) in a special case reduces to the one which is presented previously. Numerical results are reported in Tables 1, 3 and 4. The choice n = 2 root3/m provides the comparison of our numerical results given in Ta ble 2 with the results already exist in literature. (C) 2001 Elsevier Scien ce Ltd. All rights reserved.
