Three Dimensional Reattachment of a Plane Jet.

The reattachment is described of a plane jet onto a plate whose intersection with the exit plane of the jet nozzle is not parallel to the latter. This reattachment is three-dimensional and the flow under the jet forms a vortex which ends either on a lateral wall, or on the plate near the attachment line, depending on the relative values of the geometric parameters. A quasi-two-dimensional theory has been developed which gives the position of the reattachment line with reasonable precision.
