Abstract
The flow quality of three large, industrially used wind tunnels is investigated. The non-realizability of a complete evaluation concerning the influences of the wind tunnel turbulence on the laminar to turbulent boundary layer transition and/or the development of the turbulent boundary layer on models is discussed. As a new approach to the problem transition measurements on the DFVLR 1:6 prolate spheroid were carried out for axisymmetric flow conditions in three different wind tunnels at similar free-stream Reynolds numbers. Supplementary measurements of turbulence quantities by means of hot-wire anemometers and microphones lead to detailed information about the velocity and pressure fluctuation levels and enabled us to interpret the deviations in the transition locations measured in different facilities on the prolate spheroid.
