The ice and multi-phase wind tunnel Braunschweig (Braunschweig Icing Wind Tunnel BIWT) is a Göttingen type of wind tunnel with a test section cross-section of 0.5m x 0.5m. The maximum speed is 40m/s, the duct temperature can be regulated between -20°C and 30°C. The wind tunnel has a spray system for injecting water droplets, as well as a system for introducing naturally growing ice crystals for freezing experiments with supercooled water droplets, ice crystals and mixed phase conditions.
The BIWT is a Göttingen type of wind tunnel, which is equipped for the investigation of multiphase flows and icing. In the modular, closed test section, tests on profiles, probes, but also vehicle parts can be carried out. The refrigeration system ensures constant temperatures down to -20°C. Two spray systems provide droplets with different diameters, with which investigations into droplet freezing are possible. A system for blowing in artificially generated ice crystals enables the investigation of ice crystal freezing on warm surfaces. A detailed publication on the BIWT can be found here.
