Abstract

The boundary-layer flow just upstream of the trailing edge of a flat plate is studied when a free streamline is attached to the edge. The separation at the edge occurs with an infinitely favourable pressure gradient and is characterized by a skin friction which is proportional to the inverse eighth power of the distance from the edge. The proportionality factor for the first-order term is independent of the upstream boundary-layer flow. The streamwise velocity profile at separation is non-analytic near the wall Y = 0, and starts with the term $Y^{\frac{2}{3}}$.
