Abstract
A careful documentation of the development of leeward vortices, horn vortices and separation bubbles over a hemisphere-cylinder is presented. Flow visualization, static pressure measurements and seven-hole-probe velocity measurements were obtained to provide a comprehensive picture of the flow at angles of attackα=0 to 45°. Skin-friction line topographies and static pressure data are presented. The results indicate that the development of the leeward vortices is strongly affected by the nose structures. Small disturbances on the nose result in steady wake asymmetries.
