Effect of Microjet Injection on Supersonic Jet Noise

Year: 2010

Type: conference-paper

Abstract: The effect of microjet ( jet) injection on the noise from supersonic jets is investigated.Three convergent-divergent (C-D) nozzles and one convergent nozzle, all having the same exit diameters, are used in the study.The jets are injected perpendicular to the primary jet close to the nozzle lip from six equally-spaced ports having a jet-to-primary-jet diameter ratio of 0.0054.Effects in the overexpanded, fully expanded as well as underexpanded flow regimes are
