A modified Monte Carlo method is suggested to reduce the computing time and improve the convergent stability of the iteration process. This method succeeds the advantages of the usual Monte Carlo method, that is, adaptability to the complex geometry of the heat transfer system and to the variable property problem. And in this method, the numbers of the radiative bundles emitted from the control elements are proportional to the difference between the emissive energy by two successive iterative turns and the other kind of bundle is emitted to correct the variation of the radiative property between two iterative turns. The analytical examples show that this method is able to reduce the computing time remarkably and to improve the convergent stability sufficiently.
