Measurement of tip penetration of confined high-density transient jets by laser beam deflection

Abstract

The penetration of high density transient jets injected into a quiescent chamber containing air at atmospheric temperature and various pressures has been measured in terms of laser beam deflection. The sensitivity of the technique is quantified and the rate of jet penetration shown to increase with jet to chamber density ratio, decrease with chamber pressure and vary with downstream distance from the nozzle.
