A numerical method for solving the equation of radiation transfer in plane and spherical geometries
Abstract
A computational scheme for solving the stationary spectral equation of radiation transfer, without allowance for scattering, is proposed which is applicable for any optical thickness. Finite-difference expressions of the integral relation method allow the use of approximate temperature profile and angular variable; they also allow averaging with respect to the angle and frequency. Results of numerical calculations for several test problems in radiation gas dynamics are presented.
