WT284 (45 m/s) University Eindhoven

Referenceproject WT284

University of Eindhoven
The WT284 wind tunnel was built for the University of Eindhoven. The wind tunnel is used for boundary layer investigation and is characterized by a large measuring chamber, the expanding corners as well as the long diffuser and the low degree of turbulence.

  • Contraction of 5
  • Expanding corners
  • Long diffuser
  • Very good turbulence level
  • long test section

Product description
Basic structure
The WT284 consists of a steel profile welded construction and galvanized sheet metal. The additional painting gives the wind tunnel an attractive appearance and is also protected against corrosion.
The WT284 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 diffuser, whose small opening angle counteracts flow separation, opens into the expanding large corners. The wind tunnel has a large sieve chamber. This contains three sieves at an optimal distance from one another. These non-split stainless steel sieves can be separated from the sieve chamber 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 3 meter long test section with a cross section of 200x300 millimeters.
