一种新的运动激波--非定常边界层相互干扰现象

本文探讨了一种新的激波－非定常边界层相互干扰现象，这种激波－边界层干扰现象既不同于定常激波－边界层干扰现象，又不同于激波在端面反射后与该激波所诱导的边界层之间的干扰现象，而是运动激波与稀疏波和第一激波所诱导的非这常边界层之间的干扰现象，本文对这种现象用微波动力学理论进行分析，并把这种干扰现象看成激波的绕射现象，同时在稀疏波破膜的双驱动激波管中进行实验观察，最后把理论分析与实验观察进行了比较。

A New Type of Interaction of a Moving Shock with an Unsteady Boundary Layer

In this paper, a new type of interaction of a moving shock with an unsteady boundary layer had been studied theoretically and experimentally. This type of shock wave and boundary layer interaction describes a moving shock interacts with an unsteady boundary layer which is induced by another shock wave and rarefaction waves. So it is different from the interaction of a stationary shock with steady boundary layer, also different from the interaction of a reflected moving shock on the end of a shock tube with an unsteady boundary layer induced by an incident shock. The geometrical shock dynamics was used for the theoretical analysis to the shock wave and unsteady boundary layer interaction, and a double driver shock tube with rarefaction waves bursting diaphragm was used for the experimental investigation.
