The influence of the laminar–turbulent transition on the interaction between the shock wave and boundary layer at a low supersonic Mach number

Abstract

An experimental study is devoted to the problem of the interaction between the shock wave and boundary layer. The influence of the approaching boundary layer state on parameters of the interaction region is studied by use of measurements of velocity fields. It is shown that the case in which the interaction occurs near the zone of the laminar–turbulent transition in the boundary layer is optimum. The possibility of controlling for the interaction by means of turbulizers is studied.
