Towards quality assurance for wind tunnel tests: A comparative testing program of the Windtechnologische Gesellschaft

Abstract Recently, comparative wind-tunnel tests have been initiated by the Windtechnologische Gesellschaft WTG . Twelve institutes are participating in this program and have performed surface pressure measurements on a cubic model and some dispersion experiments. The elaborated results exhibit a certain scatter which is partly due to different simulations of the given full-scale situations. A reduced sample of all pressure measurements has been selected ignoring those results with major deviations to the average. The pressure difference between the front and rear face of the cube has been applied as an indicator for erroneously used dynamic and static reference pressures. The statistics of the reduced sample is listed.
