A Feasibility Study of Collaborative Multi-facility Windtunnel Testing for CFD Validation (Etude de Faisabilite d'essais en Soufflerie Multisites Menes en Cooperation, en vue de la Validation des Calculs de l'aerodynamique Numerique - CFD)

Abstract

Between 1997 and 1999, a Working Group on the feasibility of collaborative, multi-facility windtunnel testing for the validation of Computational Fluid Dynamics Codes (CFD) has established the following results: Windtunnel tests are the main source of CFD validation but all have specific bias errors. Testing of the same model in several facilities can better establish the level of uncertainty in windtunnel tests and hence help assess possible differences between CFD and windtunnel tests. The working group, after an initial inquiry, established the need for CFD validation for fighter aircraft, transport type aircraft, missiles and helicopters. Effort and cost can be controlled efficiently and would permit the improvement of CFD Codes for considerable cost saving in future developments.
