## Abstract

A potential flow model is given for lifting, two-dimensional separated flows past bodies. Flow outside the separation streamlines is simulated in a transformed plane by simple singularities such that the streamlines separate tangentially at the given separation points and the given base pressure. The theory is developed so that any body that can be mapped to a circle can be handled. As examples of the theory, lifting flows past a flat plate, an ellipse and an aerofoil are considered. The present theory which is very simple to apply compares well with the experimental data as shown for the first two cases.
