Flowfield Characteristics of a Supersonic Jet Impinging on an Inclined Surface
TL;DR: In this article, the flowfield and noise characteristics of supersonic impinging jets are studied and the authors find that these configurations can be found in many engineering applications, such as short takeoff and land landing.
Journal ArticleDOI
Instability modes of millimeter-scale supersonic jets
TL;DR: In this paper, the authors describe the appearance of instability modes on subsonic and supersonic impinging jets produced by convergent and convergent-and divergent nozzles.
Journal ArticleDOI
Control of the noise production in a supersonic jet impinging an inclined plate using grooved surface
TL;DR: In this article , the effects of free jet and jets impinging on smooth and grooved surfaces were investigated using free-field microphones, while two dimensional (2D)-particle imaging velocimetry (PIV) was utilized to investigate the velocity fields.

Journal ArticleDOI
Flow field and noise characteristics of a supersonic impinging jet
TL;DR: In this paper, the authors examined the flow and acoustic characteristics of an axisymmetric supersonic jet issuing from a Mach 1.5 converging-diverging (C-D) nozzle and impinging on a ground plane.

The impingement of underexpanded, axisymmetric jets on perpendicular and inclined flat plates
P. J. Lamont,B. L. Hunt +1 more
TL;DR: In this article, an extensive experimental study of the flows due to underexpanded axisymmetric jets impinging on flat plates is presented, where the main emphasis is on the behavior in the first shock cell.
Journal ArticleDOI
The sound‐producing oscillations of round underexpanded jets impinging on normal plates
TL;DR: In this article, the results of acoustical and optical experiments in which "moderately"" underexpanded sonic round jets impinge on flat plates normal to the jet axis are presented and analyzed.
Journal ArticleDOI
Aerodynamic Noise and the Plane Boundary
TL;DR: In this article, the image principle is developed in a rigorous manner and the apparent paradox is resolved with the help of an extension of Lighthill's and Curle's analyses to include boundaries which are not wholly immersed in the noise generating flow.

Direct excitation of small-scale motions in free shear flows
John M. Wiltse,Ari Glezer +1 more
TL;DR: In this paper, the authors focus on direct excitation of small scales within the dissipation range of a free shear flow and demonstrate that direct small scale excitation results in enhanced energy transfer from the large to the small scales and in a substantial increase in dissipation and in the decay rate of turbulent kinetic energy.
