Abstract:

A review is presented of various techniques employed in the simulation of a jet exhaust in ground test facilities. A brief summary of the characteristics of a jet exhausting into both quiescent and moving media is presented. The importance of duplicating the initial inclination angle of the jet when conducting simulation studies is pointed out. Various scaling parameters are enumerated. A requirement for the duplication of the jet pressure ratio, jet momentum, and several parameters is indicated. Experimental data are also presented which verify the importance of these parameters in simulation studies. One method of selecting the geometry and test conditions for a simulation model in order to account for a difference between model and full scale and still duplicate the important similarity parameters, is presented.
