TOWARDS QUALITY ASSURANCE FOR WIND-TUNNEL TESTS - A COMPARATIVE TESTING PROGRAM OF THE WINDTECHNOLOGISCHE-GESELLSCHAFT

Recently, comparative wind-tunnel tests have been initiated by the Win dtechnologische 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 ex hibit a certain scatter which is partly due to different simulations o f the given full-scale situations. A reduced sample of all pressure me asurements has been selected ignoring those results with major deviati ons to the average. The pressure difference between the front and rear face of the cube has been applied as an indicator for erroneously use d dynamic and static reference pressures. The statistics of the reduce d sample is listed. (C) 1998 Elsevier Science Ltd. All rights reserved .
