基于热辐射传输的光路可逆性原理,对求解热辐射传递的蒙特卡罗法的统计模式进行了改进。改进后的蒙特卡罗法利用可逆关系对样本同时进行正向和反向统计计算,提高了计算效率。比较了新型统计模式下的蒙特卡罗方法和传统蒙特卡罗法方法的性能,结果表明新型统计模式下的蒙特卡罗法相对传统蒙特卡罗法计算性能得到了提升。 Based on the principle of reversible optical path of heat radiation, the statistical model of Monte Carlo method for solving thermal radiation transfer is improved. The improved Monte Carlo method uses the reversible relation to carry on the forward and reverse statistical calculation to the sample at the same time, has raised the computational efficiency. The performance of the Monte Carlo method and the traditional Monte-Carlo method under the new statistical model are compared. The results show that the Monte Carlo method under the new statistical model has higher computational performance than the traditional Monte Carlo method.
