A fast algorithm is developed to solve radiative heat transfer problems is non-gray gas system surrounded by gray walls. In the problem, the distribution of the gas temperature and the wall heat flux in non-gray gas are estimated. In the present study, the time consuming Monte Carlo method is used only outside the iterational loop of the temperature convergence. For the purpose, the Rd values, the ratio of the radiative energy absorbed by an element to the energy emitted from a source element, are separated into two parts, the absorption-coefficient-dependent part and independent part. The calculated values of Rd are used as the input data for direct exchange areas for the zone method to obtain total exchange areas. The new method reduces the computation time by one sixth compared to the conventional Rd method. Therefore, the fast Rd method combined with zone method is advantageous for the analysis is non gray gas systems. Comparison between the results of the present method and exact solution shows the validity of the present method.
