A Remark on Improving Convergence of the Simle Iteration Method in Radiative Transfer Problems

https://doi.org/10.56304/S2079562922010420

Abstract

The paper briefly describes a modification to the simple iteration method as applied to the system of nonstationary spectral radiative heat transfer equations in kinetic model. The modification involves an additional stage where the integral intensity is adjusted on the basis of information accumulated at earlier stage of kinetic equation calculation. This allows us to more accurately consider how the solution evolves and thus improve convergence of iterations. As an illustration, results of two test problems in slab geometry are provided.
