Influence of the energy dissipation rate in the discharge of a plasma synthetic jet actuator [PDF]

Journal of Physics D: Applied Physics, 2011
A promising actuator for high-speed flow control, referred to as a plasma synthetic jet (PSJ), is being studied by the DMAE department of the ONERA, and the Laplace laboratory of the CNRS, in France. This actuator was inspired by the ‘sparkjet’ device developed by the Johns Hopkins University Applied Physics Laboratory.

Characterisation of plasma synthetic jet actuators in quiescent flow

Journal of Physics D: Applied Physics, 2016
An experimental characterisation study of a large-volume three-electrode plasma synthetic jet actuator (PSJA) is presented. A sequential discharge power supply system is used to activate the PSJA. Phase-locked planar particle image velocimetry (PIV) and time-resolved Schlieren imaging are used to characterise the evolution of the induced flow field in ...
