Abstract
Abstract : The boundary layer separation process associated with the flow field around a slender body of revolution at moderate to high angles of attack was investigated. Based on extensive comparison with existing two-dimensional, turbulent separation data, flow separation criteria by Stratford, and Sandborn and Liu were selected for the slender body calculations. The two primary axial separation lines were obtained by applying the separation criteria to the measured surface pressure distributions in numerous crossflow planes. The location of the origin of the asymmetric vortices were predicted by applying Stratford's separation criterion to the pressure distribution along the previously calculated axial separation line. Good agreement between the analytical and experimental points was obtained. Correlation between the side force maxima or minima and the location of the origin of the axisymmetric vortices and inconclusive. The need for more detailed experimental data is discussed.
