Passive scalar mixing downstream of a synthetic jet in crossflow [PDF]

open access: yes, 2008
An experimental investigation on passive scalar mixing due to the interaction of a synthetic jet with a thermal boundary layer is presented. From velocity measurements, performed by particle image velocimetry, two jet behaviours were identified.

Agitated Turbulent Flowfield of A Circular Jet with An Annular Synthetic Jet Actuator

open access: yesJournal of Fluid Science and Technology, 2008
An agitated circular turbulent jet with a coaxial annular synthetic jet actuator is investigated experimentally. The mean and turbulent velocities are measured by a hot-wire anemometer at a jet Reynolds number of 6400.
