New Statistical Mode of Monte Carlo Method for Radiative Heat Transfer in Medium

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。

A new statistical mode of Monte Carlo method for radiative heat transfer in medium is developed, which is based on both the reversibility of bundle trajectory and the reciprocity of thermal radiative energy exchange. The mode is an improvement of statistical calculation of the traditional Monte Carlo method. The performance parameter of radiative transfer coefficients are compared with the traditional Monte Carlo method. The analysis shows the superiority of improved Monte Carlo method to the traditional Monte Carlo method.
