Effect of Mach Number on Shock Oscillations in Supersonic Diffusers

  • Conference paper
  • First Online:
30th International Symposium on Shock Waves 1

Abstract

Unsteady characteristics of shock wave oscillations are one of the most prevalent phenomena occurring in a supersonic diffuser. In such oscillations, significant boundary layer separation leads to a highly unsteady flow field resulting in inlet instability, aircraft buffeting, and aero-structure fatigue. From an engineering point of view, this phenomenon can have a significant impact on performance of supersonic diffusers operating near critical mass flow because of the complex interaction between the boundary layer and many shock waves. This includes a shock-wave/turbulent boundary-layer interaction (SBLI) followed by a subsonic region with an adverse pressure gradient and rapidly thickening boundary layer.
