Introduction and Paper Review

In this chapter, an introduction of shock-boundary layer interaction (SBLI) is given. A paper review about the driven mechanism of pressure fluctuation caused by shock induced flow separation on a ramp corner is presented and a research history on micro vortex generator (MVG) is briefly reviewed. In particular, a series of new findings made by the LES team at the Center of Numerical Simulation and Modeling led by Dr. Chaoqun Liu under the support of US Air Force Office of Scientific Research (AFOSR) is briefly reported. These new findings are milestone work which have made a breakthrough in understanding the physics of SBLI, shock-vortex ring interaction, control of shock induced flow separation and noise generation.
