A mathematical method for calculating the heat flux distribution of the radiant heat flux in the combustion chamber is presented. The Monte Carlo method is not used to solve the multiple integral of radiant energy equation directly. Instead, the statistical value of the integral is calculated by constructing the probabilistic model. Which can well be used to calculate the space radiation angle coefficient of complex body.Combining the multi-zone multi-zone model of in-cylinder radiation, the ω-type combustion chamber is mathematically approximated and the calculation result of the distribution of radiative heat flux in the cylinder is given
