本文提供了描述圆柱体周围可压缩流体流动的新结果。研究仅限于雷诺数约为 10 秒的亚音速和跨音速流动。实验表明，圆柱体上的流动与近尾流中形成的涡街之间存在强耦合。使用与不稳定压力测量同步的高速可视化来研究这种现象。对各种耦合方式进行了分类，并获得了涡街期间不同时间的瞬时压力分布。从这些元素中可以推断出不稳定力。
This paper provides new results describing compressible fluid flow around a cylinder. The investigation was restricted to subsonic and transonic flow at Reynolds numbers of about 10s. The experiments showed that a strong coupling exists between the flow over a cylinder and the vortex street formed in the near wake. The phenomenon was investigated using high-speed visualization synchronized with unsteady pressure measurements. Various coupling regimes were classified and instantaneous pressure distributions were obtained at different times during the vortex street period. From these elements it was possible to deduce the unsteady force.
