摘要
报告了对方形横截面通道中形成的超音速流进行数值研究的结果。研究考虑了由相互成直角排列的四个压缩楔形成的收缩入口段和随后的恒定截面通道组成的配置。在机头压缩楔上形成的初始冲击波沿着扫过线在配置的二面角上成对相交，并在下游形成一个由一般三维位置的反射冲击波和随后的相互作用冲击波组成的复杂系统。这些数据是在自由流马赫数 M = 2-4 的超音速范围内，压缩楔角为 3° 和 8°，初始冲击波在构型的二面角上有规则和不规则相互作用的流动中获得的。
Numerical simulation of internal flows with three-dimensional swept interaction of shock waves
Results of a numerical study of supersonic flows formed in channels with a square cross section are reported. Configurations consisting of a constricting entrance section formed by four compression wedges aligned at a right angle to each other and a subsequent channel with a constant cross section are considered. The initial shock waves formed on the nose compression wedges pairwise intersect each other in dihedral corners of the configuration along the swept lines, and a complex system of reflected and subsequent interacting shock waves of the general three-dimensional position is formed further downstream. The data are obtained in a supersonic range of freestream Mach numbers M = 2–4 for compression wedge angles of 3° and 8° in flows with both regular and irregular interaction of the initial shock waves in dihedral corners of the configuration.
