Asymmetric vortices on a slender body of revolution

the symmetric and asymmetric leeward-side flowfields on an inclined ogive cylinder have been investigated using a number of experimental techniques. Naturally occurring and perturbed flowfields were studied at a moderate Reynods number and at many incidence angles. By close examination of the steady side-force behaviour at different roll orientations of the tip, it has been established that micro variations in the tip geometry of the model have a large influence on the downstream development of the flowfield. Under certain conditions a bi-stable flowfield was observed.
