摘要: 利用水的简化物态方程讨论了水中斜激波波后流动马赫数、密度比、压强增量及冲击角与来流马赫数的关系,给出了一个无量纲化的激波极线方程;对附体激波转变为脱体激波及波后流动为等声速流的条件进行了讨论。Abstract: The relation among downstream Mach number, density ratio, pressure increase, shock angle and upstream Mach number are discussed based on a simple equation of state for water. A dimensionless shock polar equation is presented. The critical conditions for the turning of attached oblique shock wave to detached shock wave and the downstream flowing at the velocity of sound are discussed.
