Subsonic Suction Wind Tunnel

Teaching objectives

The wind tunnel allows a wide range of spectacular experiments, including:

  • Measurement of flow velocity and gradients in the test section.
  • Measurement of pressure differentials around an aerofoil.
  • Study of the pressure gradient around a cylinder
  • Using additional equipment.
  • Measurement of lift and drag using a 2- component balance.
  • Measurement of lift, drag and pitching moment with a 3-component balance


Technical specifications

The wind tunnel is bench-mounted to allow easy mounting of the instruments and models.
It consists of:

  • A carefully designed contraction to provide uniform air flow.
  • A transparent test section with panels prepared for the location of probes.
  • A diffuser and honey comb connecting the test section to the suction fan.
  • An axial fan and motor assembly mounted on a separate metal support, to provide isolation from vibration in the test section. The variable speed fan is controlled to provide air speed variation from 1 – 45 m/s.
  • A diffuser for return of air to the laboratory.
  • The wind-tunnel is of metal with a stoved finish and PVC construction.
  • Test section: 230 x 230 x 500 mm.
  • Maximum airflow: 45 m/s.
  • Fan power: 3 kW
