In this paper, we provide the experimental evidence of a free-standing conical shock and the compressive confocal characteristics region in the Busemann intake flow. The experiments are carried out in the DRDC Trisonic Wind Tunnel at freestream Mach number 3.0 with a Busemann ring model. The Taylor-McColl equations are integrated to obtain the Busemann streamline and hence the inner surface of the Busemann ring. The CFD analysis of the flow using a locally adaptive unstructured Euler finite-volume code is in agreement with the experiments.

独立式锥形冲击

在本文中，我们提供了 Busemann 进气流中独立锥形冲击和压缩共焦特征区域的实验证据。实验在自由流马赫数 3.0 的 DRDC Trisonic 风洞中使用 Busemann 环模型进行。对 Taylor-McColl 方程进行积分以获得 Busemann 流线，从而获得 Busemann 环的内表面。使用局部自适应非结构​​化欧拉有限体积代码对流动的 CFD 分析与实验一致。
