Study of Transmission Probability Method Based on Triangle Meshes

摘要: 研究了基于三角形网格的中子输运方程穿透概率方法。网格子区内部中子源采用平源分布,子区界面中子角注量密度空间分布设为均匀,角度分布采用简化4P₁近似,并采用一种按照非结构网格编码顺序进行网格扫描的新方法。编制了适应于二维任意形状几何中子输运特征值问题求解的程序TPTRI,对一些二维输运基准问题作了计算。与MG-MCNP3B、SURCU、TEPFEM等程序结果进行了比较分析,结果吻合很好。

Abstract: Transmission Probability Method based on triangle meshes is studied in this paper.The inte-rior source is assumed to be isotropic in angular distribution and constant in spatial distribution.The surface angular flux is assumed to be with simplified 4P₁ approximation in angle and average in space.A new grid sweep process based on unstructured-mesh coding number is adopted.TPTRI program is encoded which can be applied to the solution of neutron transport of arbitrary two-dimensional geometry.Several benchmark problems are calculated and the results are compared with MG-MCNP3B,SURCU and TEPFEM programs.The numerical analyses show that the results of TPTRI are in good agreements with that from other programs.
