Measurements of Kelvin-Helmholtz instabilities in a supersonic shear layer

Experiments have been performed in a new supersonic shear layer facility in which two streams of air are produced in adjacent supersonic sliding block nozzles. Measurements show that the glow discharge excitation has a significant effect on the shear layer in terms of growth rate and spectral conten...

Zusammenfassung:	Experiments have been performed in a new supersonic shear layer facility in which two streams of air are produced in adjacent supersonic sliding block nozzles. Measurements show that the glow discharge excitation has a significant effect on the shear layer in terms of growth rate and spectral content of the fluctuations.
