Inception of asymmetric vortex flow over slender body

摘要：

This paper reports an investigation of onset of asymmetric vortex ow over slender bodies through pressure measurements on two models which are of different diameters and different fineness ratios in a low-speed low turbulence level (0.08％) wind-tunnel. In the paper, effect of perturbation, as well as Reynolds number, on the variation of onset angle of attack was discussed. Moreover, the onset AOAs on forebody and afterbody sections were compared.
