Behavior of the laminar boundary layer for periodically oscillating pressure variation

An extract is presented of theoretical results from a more detailed report on the growth of the laminar boundary layer on an undulated surface. For a surface which was undulated about the mean of a flat plate, the drag was shown to be appreciably less than that for a flat plate at very low Reynolds numbers; however, the onset of transition on the undulated plate occurred at lower Reynolds numbers than on the flat plate.
