Abstract

The aim of this paper is to present new mathematical developments to modeling radiation in flames. A Monte Carlo Method based on a Net Exchange Formulation is used to calculate the radiative source term. The advantage of this method is that, still providing reference solutions, the net exchange formulation together with a choice of adapted probability density functions allows one to significantly decrease the number of random generations while keeping small standard deviations. Some 1-D and 2-D code validation test cases are presented in this paper as a step toward application of this new approach to complex geometries.
