surface streamline patterns on a spheroid have been examined at several angles of attack. most of the tests were performed at low reynolds numbers in a hydraulic flume using coloured dye to make the surface flow visible. a limited number of experiments was also carried out in a wind tunnel, using wool tufts, to study the influence of reynolds number and turbulent separation. the study has verified some of the important qualitative features of three-dimensional separation criteria proposed earlier by maskell (1955), wang (1970) and others. the observed locations of laminar separation lines on a spheroid at various incidences have been compared with the numerical solutions of wang and show qualitative agreement. the quantitative differences are attributed largely to the significant viscous-inviscid flow interacting which is present, especially at large incidences
