Product description

Basic structure
The WT359 consists of a welded steel profile construction and sheet steel. The scratch-resistant 2K paint finish gives the wind tunnel an attractive appearance and protects it from corrosion. Inspection flaps in all relevant segments allow easy access to the inside of the wind tunnel.

The WT359 is driven by a vibration-decoupled axial fan. The fan, which is mounted on spring anti-vibration mounts, is connected to the wind tunnel via canvas flanges. This ensures low-noise system operation.

The long diffusers, whose small opening angle counteracts flow separation, open into non-expanding corners. The wind tunnel has an extra-large screening chamber. This contains two sieves at an optimal distance from each other. These non-divided stainless steel sieves are accessible via inspection hatches for easy cleaning. A honeycomb rectifier with a length-to-diameter ratio of 8:1 further reduces the swirl of the flow. In a nozzle whose nozzle geometry corresponds to a fifth-order polynomial, the flow is accelerated 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 into the extended nozzle outlet. The interior of the closed test section can be seen through glass windows. The recording of flow characteristics using optical measuring methods, e.g. PIV (Particle Image Velocimetry) or LDA (Laser Doppler Anemometry) is possible without any problems. The test section can optionally be equipped with a wind tunnel scale.
