Abstract : Based on recent symmetry-plane boundary layer solutions, new separation patterns over an inclined body of revolution are presented. Support by experimental evidence as well as differences from other predictions in the literature are noted. Existing three-dimensional separation criteria are mostly inapplicable, and the resulting patterns found are compatible only with Maskell's general description of separation; i.e., a combination of the free vortex layer type and a bubble type. For a not-too-blunt body, a bubble type prevails at low incidence, and a free vortex layer type dominates at high incidence. At extremely high incidence or for very blunt body, a bubble type prevails again. (Author)
