Wind tunnel investigations of vortex breakdown on slender sharp-edged wings
Year: 1968
Abstract: Systematic wind tunnel investigations of vortex breakdown have been conducted on sharp-edged delta and modified delta wings with sweep angles from 45° to 850 at Reynolds numbers of about 1 x 106, utilizing a schlieren system for flow visualization. Vortex breakdown positions are presented as a function of angle of attack and seep. Results agree well with the limited amount of previously published data For the very slender wings (750 to 850 sweep), initial breakdown was nearly independent of sweep, a result not anticipated by extrapolation of previous data.
