Cryogenic Wind Tunnel / Quiet Nozzle
In the current transonic or supersonic wind tunnels, the Reynolds numbers and turbulence intensity are different from those in actual conditions, causing the problems of the turbulence transition and separation points being inconsistent between the wind tunnel test results and the actual machine tes
To solve these problems, MHI Group has engaged in the research and development of cryogenic wind tunnels which lowers the temperature of the airflows to bring the Reynolds number of the measurement closer to the actual machine test, and supersonic, quiet nozzles which can generate less turbulent airflows.
