Synthetic jets

A Glezer, M Amitay - Annual review of fluid mechanics, 2002 - annualreviews.org
▪ Abstract The evolution of a synthetic (zero-net mass flux) jet and the flow mechanisms of its
interaction with a cross flow are reviewed. An isolated synthetic jet is produced by the …

Dynamics and instabilities of vortex pairs

T Leweke, S Le Dizès… - Annual review of fluid …, 2016 - annualreviews.org

Vortex induction and mass entrainment in a small-aspect-ratio elliptic jet

CM Ho, E Gutmark - Journal of Fluid mechanics, 1987 - cambridge.org
A passive technique of increasing entrainment was found by using a small-aspect-ratio
elliptic jet. The entrainment ratio of an elliptic jet was several times greater than that of a …
