Abstract

Theme A integral boundary-layer method is extended to calculation of separated turbulent boundary layers by treating the pressure as a dependent variable and prescribing the wall shear variation. The boundary-layer method and a suitable potential flow method are used in an iterative procedure to produce a method for predicting the characteristics of separated flows. The interaction between the boundary layer and the inviscid flow is accounted for by augmenting the physical surface by the boundary-layer displacement thickness. Good comparisons are shown between the theory and data for a separated turbulent boundary layer on the wall of a transonic wind tunnel.
