Summary:A finite element solution of the radiative heat transfer in participating media is presented. The expensive direct numerical treatment of the integrodifferential equations of radiation is avoided by employing the moment method, which allows the derivation of an approximate local field equation for the radiation intensity. This makes the procedure convenient for use in combined-mode heat transfer problems, where the coupling of the radiation model with the iterative convective flow solution is required. The approach is assessed by investigating several numerical examples.
