其中一种高分辨率的迎风格式“MUSCL WITH Roe‘s Average”被应用于涡流模拟。本文考虑了两个例子。其一是前缘分离涡绕边三角翼的流动。另一种是大迎角超音速绕过空间平面布局。与中心差分解的比较表明，该迎风格式的耗散较小，对涡流具有较好的分辨率。因此，对于高雷诺数下的涡流数值模拟，建议使用适当的展开格式，而对计算结果的验证对于涡流数值模拟尤为重要。
One of the high-resolution upwind schemes called "MUSCL with Roe's average" is applied to vortical flow simulations. Two examples are considered. One is the leading-edge, separation-vortex flow over a strake-delta wing. The other is a high angle-of-attack supersonic flow over a space-plane-like configuration. The comparison with the central-difference solutions indicates that the present upwind scheme is less dissipative and thus has better resolution for the vortical flows. Thus, it is concluded that the use of proper unwind schemes is recommended for vortical flow simulations at a high Reynolds number, and verification of computed result is especially important for vortical-flow simulations.
