本文对平面激波与圆柱涡的相互作用进行了计算研究。我们使用一个特别强大的高分辨率冲击捕获计划，Marquina的计划，以获得高品质，高分辨率的相互作用的数值模拟。在一个非常强的激波/涡流相遇的情况下，我们观察到在下游区域的流场的严重重组，这似乎主要是由于激波的强度。通过对数值试验数据的分析，研究了涡量产生的驱动机制。
We perform a computational study of the interaction of a planar shock wave with a cylindrical vortex. We use a particularly robust High Resolution Shock Capturing scheme, Marquina's scheme, to obtain high quality, high resolution numerical simulations of the interaction. In the case of a very-strong shock/vortex encounter, we observe a severe reorganization of the flow field in the downstream region, which seems to be due mainly to the strength of the shock. The numerical data is analyzed to study the driving mechanisms for the production of vorticity in the interaction.
