Abstract
This paper deals with the end-effect problem encountered in the wake vortex researches in test facilities with limited length. The disturbances produced during the launching and recovering of a/c models may propagate along the vortex core and introduce a helical instability which will burst off the vortex core. When the disturbances reach the measurement region, the results will be spoiled. Investigations were made in a water towing tank, which was instrumented with a stereo PIV system and visualization devices. Methods for alleviating the end-effect were studied and one effective setup was patented.
