Abstract: The problem being considered is the abrupt loss of lift/downforce and the increase in drag caused by 3-dimensional flow separation over wings. The displacement thickness of a flow that separates grows dramatically, changing the external potential flow and pressure field. The alteration of the pressure field causes a rise in pressure drag, and if it is severe enough, it may also cause loss of lift and stall. In this study, flow over a wing with and without vortex generators is analyzed computationally.
