Heat and Fluid Flow Properties of Circular Impinging Jet with a Low Nozzle to Plate Spacing. Improvement by Nothched Nozzle.

Effect of Nozzle-Plate Distance on Acoustic Phenomena from Supersonic Impinging Jet

This study investigates the effect of nozzle-plate distance on the acoustic phenomena from a correctly expanded supersonic jet impinging on an inclined flat plate. In the authors’ previous study, the overall sound-pressure-level (OASPL) in the direction almost perpendicular to the plate from the impingement region became highest when the nozzle-plate distance was 15D (D, the nozzle exit diamete...

Noise Generation in the Near-Nozzle Region of a Chevron Nozzle Jet Flow

This paper reports on the simulation of the near-nozzle region of a moderate Reynolds number cold jet flow exhausting from a chevron nozzle. The chevron nozzle considered in this study is the SMC001 nozzle experimentally studied by the researchers at the NASA Glenn Research Center. This nozzle design contains six symmetric chevrons that have a five-degree penetration angle. The flow inside the ...

Hybrid RANS/LES of plane jets impinging on a flat plate at small nozzle-plate distances

A k-ω based hybrid RANS/LES (Reynolds-averaged Navier–Stokes/large eddy simulation) model is tested for simulation of plane impinging jets at various nozzle-plate distances (H/B), where H is the distance and B is the slot’s width) and various Reynolds numbers (based on the slot’s width and the velocity in the symmetry plane). The studied combinations are H/B = 2 for Re = 10 000, H/B = 4 for Re ...
