摘要: 构造了二维柱几何条件下中子输运方程的非匹配网格,解决二维中子输运间断有限元方法在非匹配网格上的扫描排序及边界流的计算问题,使二维柱几何中子输运方程可以在非匹配网格上应用间断有限元方法顺利计算。结果表明,二维中子输运非匹配网格上的间断有限元方法计算结果正确,能保持原物质边界,在保持一定精度的基础上可减少计算量,节省计算时间。Abstract: This paper constructed a no matching mesh for neutron transport equations under 2-D cylindrical geometry,and designed a new sweep algorithm and a new method for computing the mesh boundary flows for neutron transport equations on no matching mesh.The new methods can assure the neutron transport equations to be solved successfully using the discontinuous finite element method on no matching mesh.
