BOUNDARY SIMULATION PARAMETERS FOR UNDEREXPANDED JETS IN A QUIESCENT ATMOSPHERE

Abstract

A summary of some of the parameters now in use to obtain jet boundary simulation in a quiescent atmosphere is presented. The shortcomings of these parameters are depicted by showing jet boundaries calculated to an axial distance of ten nozzle exit radii by an approximate technique. Using this approximate technique as a basis for evaluation, a new parameter is presented which, when used in conjunction with the initial inclination angle of the jet, provides a means of specifying jet operating parameters for the simulation of jet boundaries. Methods for preselecting model jet operating and geometric conditions are also discussed.
