| 摘 要： | 本文给了一种适用于任意非结构网格的有限体积/有限元法的混合算法用于求解多维半透明吸收、发射、散射性灰矩形介质内的辐射传递.该方法使用有限元法进行角度离散,有限体积法进行空间离散.与基于辐射传递离散坐标方程的方法不同的是,该方法在迭代求解的过程中,针对每一个空间体元,所有角度方向的辐射强度同时耦合求出.通过两个算例验证了该解法的正确性.

| Abstract: | An unstructured hybrid finite volume/finite element method(FVM/FEM)is presented to solve the radiative transfer problem in multidimensional absorbing-emitting-scattering semitransparent media.The spatial discretization is carried out using the finite volume method,while the angular discretization is performed using the finite element method.Different from the methods based on the traditional discrete ordinate formulation,this method solves the radiative intensity of all the direction for one control volume at the same time.Two cases of radiative transfer were taken test examples to verify the performance of the FVM/FEM. |
