摘　　要：双向蒙特卡罗法继承了正向蒙特卡罗法和反向蒙特卡罗法两种方法的优势,不仅可以解决各种各向异性散射问题,还能简易直接地解决辐射能量的方向性和定位置问题。为了验证双向蒙特卡罗法模拟热辐射传递,与文献中其它方法计算结果进行了比较。最后,利用双向蒙特卡罗法模拟计算圆柱形参与性介质中的辐射换热。Coupling the advantages of forward and backward Monte-Carlo, Bi-directional Monte-Carlo could be used to solve the anisotropic scattering problem, and further the case of detecting radiation signals at some selected positions and/or given direction is obtained simply. To validate the Bi-directional Monte-Carlo simulation for radiative heat transfer, the solution obtained from this method is compared with that from other methods. After this validation, the Bi-directional Monte-Carlo is employed to solve radiative heat transfer in cylindrical participating medium.
