A comparison between synthetic jets and continuous jets

Experiments in Fluids, 2003
Experimental measurements and flow visualiza- tion of synthetic jets and continuous jets with matched Reynolds numbers are described. Although they have the same profile shape, synthetic jets are wider and slower than matched continuous jets. The synthetic jets are ex- amined at higher Reynolds numbers than previously studied and over a large range of ...

Manipulation of an axisymmetric jet using continuous control jets

Journal of Turbulence, 2006
The mechanisms associated with the interaction of an axisymmetric free jet (d e = 4 mm; Re U e = 26 500 and 6600) with two continuous control jets on mixing, spreading and direction were examined experimentally. The flow field was visualized and measured using particle image velocimetry, where the interaction of the main jet with the control jets was ...

The Continuous Jets of Cygnus X-1

Astrophysics and Space Science, 2001
A resolved jet-like radio-emitting structure on mas scales has been found in Cygnus X-1. The jet emission is relatively smooth, and does not show the knots and blobs seen in Cygnus X-3, SS433 and GRS1915+105. This suggests that the jet production mechanism in Cyg X-l is continuous, with the steady production of the energetic electrons and magnetic ...
