摘要

In the present study, a hybrid passive-active flow control method is used to investigate the interaction between a swept shock wave (SSW) generated by a swept compression wall, and a supersonic wake formed by a wake generator (WG), using a three-dimensional finite volume code. In order to detect the turbulence in the flow behavior, the Reynolds stress model (RSM) is used. Furthermore, dynamic mesh adaptation (DMA) and full multigrid (FMG) techniques are used to better predict the flow structure. The numerical simulations are validated with available data and acceptable agreements are found. After ensuring the accuracy of the numerical code, the effects of the variations in the wake generator's height and temperature, as a hybrid passive-active flow control method, on a swept shock wave and a supersonic wake are investigated. The results indicate that any change in the height and temperature of the wake generator affects the Mach number distribution, the static and the stagnation pressures, as well as the shock's position.
