Abstract: This study focuses on both the development of the turbulent boundary layer in supersonic flow over a flat plate, the distance required for it to invade the entire section of the plate, and the effects of the size of the interaction area on the development of the boundary layer. Increasing the strength of the interaction is an increase in size of the areas of interaction leading to the formation of a recirculation bubble which is an area of the head losses. For this reason, it can increase and decrease the Mach number for a reflection or Mach explains the impact of the incident shock wave with strong boundary layer. The increase and decrease the Mach number has caused the appearance of a hysteresis loop which is represented by the contours of iso fields’ density. These studies are in agreement with respect to the trial that was presented by J. Delery et al (2009). We were given another contribution and investigations of the phenomenon of wave interaction of shock / turbulent boundary layer. The model used in this study is the kw-SST model, it is considered as the most suitable for this kind of problem, with special treatment of the near-wall region. Numerical simulations were performed using FLUENT software.
