WT009 (65 m/s) Toulouse

Referenceproject WT009

Institut Clément Ader Toulouse
The WT009 wind tunnel was built for the Clément Ader Institute in Toulouse France (contact person Marc Budinger). The icing wind tunnel is characterized by high contraction, the non-expanding corners and the long diffuser and an adjoining heat exchanger module.

  • Icing wind tunnel
  • High contraction of 9
  • Nonexpanding corners
  • Long diffuser
  • Stainless steel construction

Basic structure
The WT009 consists of a stainless steel profile welded construction and stainless steel sheet. Inspection flaps in all relevant segments allow easy access to the inside of the wind tunnel.
The WT009 is driven by a vibration-decoupled axial fan. The fan, which is mounted on spring shock absorbers, is connected to the wind tunnel via canvas flanges. This ensures low-noise plant operation.
Flow preparation
The long diffusers, whose narrow opening angle counteracts flow separation, open into non-expanding corners. A module is located between the diffuser and the corner, which has been equipped with a heat exchanger by the customer. The wind tunnel is used as an icing wind tunnel. The wind tunnel has a large sieve chamber. This contains four sieves at an optimal distance from one another. These non-split stainless steel sieves are accessible via inspection flaps for easy cleaning. A honeycomb straightener with a length-to-diameter ratio of 8:1 further reduces the swirl of the flow. In a nozzle, the nozzle geometry of which corresponds to a polynomial of the fifth order, the flow is prepared and any turbulence that may be present is suppressed.
The measurement in the wind tunnel takes place in the closed test section. This is integrated in the extended nozzle outlet. The inside of the closed test section can be seen through glass windows. The recording of flow characteristics using optical measurement methods, e.g. PIV (Particle Image Velocimetry) or LDA (Laser Doppler Anemometry) is possible without any problems.
