论文摘要
本文为笛卡尔网格的二维特殊相对论流体动力学方程式开发了真正的多维HLL Riemann求解器和有限体积方案,并研究了其物理构成保护(PCP)属性。几个数值结果证明了冲击波的准确性,性能和分辨率以及所提出的PCP方案的真正多维波结构。
This paper develops the genuinely multidimensional HLL Riemann solver and finite volume scheme for the two-dimensional special relativistic hydrodynamic equations on Cartesian meshes and studies its physical-constraint-preserving (PCP) property. Several numerical results demonstrate the accuracy, the performance and the resolution of the shock waves and the genuinely multi-dimensional wave structures of the proposed PCP scheme.
