Jet Penetration and Interaction at a Sonic Throat.

Abstract

The thesis describes the results of an investigation of the throttling effects of a transverse jet when injected into a sonic throat. The process, commonly referred to as aerodynamic throttling, was studied both analytically and experimentally. An analytical model is developed utilizing momentum considerations. This model successfully predicts the measured throttling results for 90 degree injection and mainstream flow reductions up to approximately 60 percent. An experimental program is described in which a two-dimensional nitrogen jet is injected into the mainstream through slots of various widths and inclinations. Visual flow patterns are shown to qualitatively describe the nature of the interaction between the jet and the mainstream. (Author)
