Boundary Layer Test Rig

Description

  • Open wind tunnel to investigate the boundary layer
  • Research on partial load recirculation in turbo engines by using a generic model
  • Research on active boundary layer excitation
  • High variability by exchanging the rotating core

Investigation methods

  • Laser Doppler Anemometry (LDA)
  • Pinhole orifice measurement for determining the volume flow
  • Inductive distance measurement

Technology

  • Coherent Genesis MX STM – 1 W Solid state laser
  • Maximum speed of the pipe 12500 rpm
  • Maximum flow speed 41 m/s
  • Maximum volume flow 0.08 m³/s
