Journal ArticleDOI
Effect of impingement surface roughness on the noise from impinging jets
TL;DR: In this paper, the effects of roughness of the impingement plate widens the staging region of noise and the effect of nozzle-to-plate spacing distance and nozzle pressure ratio are investigated.
Journal ArticleDOI
Mitigation of impinging tones using central protrusion
TL;DR: In this paper, the authors compared the acoustic variations in jets impinging on a flat plate, and plates with a central protrusion, and found that the protrusion is more effective in reducing tones in supersonic impinging jets than the tones in subsonic impingement jets.
Journal ArticleDOI
Effect of plate inclination on the noise of impinging jets
TL;DR: In this article, a detailed directivity study of jet impinging on the inclined plate is carried out, and high speed flow visualization is performed to compare shock oscillation and tonal frequencies.
Proceedings ArticleDOI
Hysteresis effects in the impinging jet noise
TL;DR: In this paper, an experimental acoustic investigation of underexpanded free and impinging jet is carried out for various nozzle-plate spacing, and it is observed that the free jet acoustic radiation remains same for both paths but the acoustic radiations differ in some regions.
Journal ArticleDOI
Effects of passive grids on pipe and orifice jet noise
TL;DR: In this article, the effect of passive grids on the acoustic characteristics of pipe and orifice jets for different Nozzle Pressure Ratios (NPRs) was investigated for various emission angles.
