Journal ArticleDOI
Vortex pairing in a circular jet under controlled excitation. Part 1. General jet response
TL;DR: In this article, the conditions most favorable to vortex parting were determined as a function of the excitation Strouhal number, the Reynolds number, and the initial shear-layer state.
Journal ArticleDOI
Control of an axisymmetric jet using vortex generators
TL;DR: In this article, the effect of vortex generators at the nozzle exit on the evolution of a jet was investigated, and the results of an experimental investigation on the effect on the vortex generators were reported.
Journal ArticleDOI
Effect of tabs on the flow and noise field of an axisymmetric jet
TL;DR: The effect of vortex generators, in the form of small tabs projecting normally into the flow at the nozzle exit, on the characteristics of an axisymmetric jet is investigated experimentally over the jet Mach number range of 0.3-1.81 as discussed by the authors.
Journal ArticleDOI
Axis switching and spreading of an asymmetric jet: the role of coherent structure dynamics
TL;DR: In this article, the effects of vortex generators and periodic excitation on vorticity dynamics and the phenomenon of axis switching in a free asymmetric jet are studied experimentally and two mechanisms are identified governing the phenomenon.
Journal ArticleDOI
Spreading characteristics of compressible jets from nozzles of various geometries
TL;DR: In this paper, the spreading characteristics of several asymmetric nozzles, and a set of rectangular orifices are compared, covering a jet Mach number range of 0.3-2.0.
