摘要: 研究多群辐射输运计算的源迭代输运综合加速方法,通过优化灰体输运综合加速,构造了双层嵌套的输运综合加速方法.数值算例表明新方法较灰体输运综合加速进一步提高计算效率,且适用于吸收系数强间断的高维复杂几何问题.

Abstract: Convergence of source iteration is analyzed for multi-group radiative transfer calculations. A two-level nesting transport acceleration method is developed. Numerical results show speedup factors of the scheme are higher than that of GTA method. The scheme is feasible for non-rectangle grid calculations of 2D problems with large discontinuities of material properties.
Key words: multi-group radiative transfer, discrete ordinate method, source iteration, transport synthetic acceleration
