Application of flow suction for controlling the shedding of large-scale vortices at boundary-layer separation

  • A. V. Dovgal
  • A. M. Sorokin


A wind-tunnel study of the influence of flow suction on laminar boundary-layer separation behind a two-dimensional step on the surface is performed. Hot-wire measurements are carried out at low subsonic flow velocities. It is demonstrated that this method of flow control allows suppressing the formation of large-scale vortices determined by global stability properties of the separation region.
