THE INFLUENCE OF SHOCK AND BOUNDARY LAYER INTERACTION ON SHOCK TUBE FLOWS,
Abstract
During the last decade the study of the interaction between normal shocks and boundary layers in the shock tube has been carried out by many research workers. This interest has been fostered by the requirement to understand the effects that this phenomenon may have on the flow properties in the region between the reflected shock and the end of the tube. This so-called reflected shock region is important in chemical kinetics studies and as a reservoir of gas for hypersonic shock tunnels. In the paper a detailed review is given of the various analyses of the problem together with the results of experimental studies. Reflected and transmitted shock bifurcation, the rate of growth of the bifurcated foot, and the effects of transition to turbulence are discussed. The influence of bifurcation on the flow in the shock tube is assessed, especially as a mechanism for transporting cold driver gas to the end plate, causing early cooling of the gas in the reflected shock region.
