The jet in a crossflow.

A review of experimental data on jets exhausting into a crossflow is presented with particular interest for the case of a circular jet exhausting normally into a crossflow. This is followed by a survey of a number of proposed models attempting to describe this jet interference phenomenon. As a result of this survey a vortex sheet model, in which the jet is replaced by a pair of trailing vortices connected by a bound vortex sheet, is developed to predict the jet flow properties. Comparisons with experimental data, and in particular the collapse of data presented in similarity form, gives valuable support to this model. Computer programs, in Algol 60, have been developed for the calculation of flow properties and for plotting of the induced pressure distribution on a flat plate
