摘    要:本文提出一种基于蒙特卡洛法(Monte Carlo Method, MCM)的新方法在具有漫反射边界一维灰性平行平板介质中求解辐射传递方程(Radiative Transfer Equation,RTE)。该方法能以较高的方向分辨率精确地计算任意点的辐射强度而不需要辐射能量平衡。验证结果显示了该方法的有效性和正确性。并且这种方法具有的一些特点,例如不同辐射源对辐射强度分布贡献的可加性和自动满足边界条件等,使得用该方法更容易处理复杂的辐射换热并行计算问题和复杂的边界条件问题。

关 键 词:辐射传递方程  辐射强度  蒙特卡洛法  漫反射边界

Abstract:A new method proposed to solve the Radiative Transfer Equation using the Monte Carlo Method for one-dimensional gray plane-parallel media with diffusely boundary condition. By this method, the intensity with high directional resolution in any point can be obtained with high precision without the requirement of radiative equilibrium. Validation results demonstrated its validity and accuracy. Some attractive features, such as the additivity of intensity for different emitting sources and the automatically meeting the boundary conditions, make the present method more attractive in dealing with complicated radiative transfer problems by parallel computation and complicated boundary conditions.
Keywords:radiative transfer equation  intensity  Monte Carlo method  diffusely boundary condition
