Acoustic emissions from supersonic jets are of interest due to their deleterious effects on nearby personnel and structures. As development of both military and commercial supersonic aircraft continues to grow, it is essential to combat increasing noise pollution. Axisymmetric jets are highly prevalent where their aeroacoustic characteristics have...

A joint experimental and computational study is performed to quantify the effects of various expansion ratios on the flowfields and acoustic properties of a jet, issuing from a diamond-shaped nozzle. Three expansion ratios are studied corresponding to perfectly expanded, overexpanded, and underexpanded regimes, which progressively increase the far-...

At the current aspect ratio, AR = 2 , the heated and unheated jets exhibit asymmetric far-field acoustic signatu...

Acoustic emissions from supersonic jets are of interest due to their deleterious effects on nearby personnel and structures. As axisymmetric jets are highly prevalent, their aeroacoustic characteristics have been well-documented, whereas relatively few studies have examined non-axisymmetric jets. The current study focuses on the aeroacoustics of su...
