PHENOMENON OF FORMATION OF PRESSURE PULSATIONS DURING THE INCIDENCE OF THE SHOCK WAVES ON THE BOUNDARY LAYER
摘要
The internal structure of a laminar boundary layer, detached from a flat plate streamlined by a supersonic flow of a gas (M = 2), upon impact of the shock wave is studied numerically and analytically. The process of formation of the separation region is considered in the framework of the nonstationary Navier-Stokes equations. A detailed picture of the gas flow in this region with a secondary separation is obtained. The phenomenon of initiation of large-scale pressure pulsations on a wall in the separation zone in front of the incidence point of the shock wave is explained.
