Synthetic jet actuator using bubbles produced by electric discharge

Journal of Fluid Science and Technology, 2014
Over the last decade, synthetic jets suitable for micro-machinery have received attention for their potential to replace continuous jets. The development of synthetic jet actuators with, for example, a diaphragm, a piston, a piezoelectric element, or a ...

Effect of orifice shape on three-dimensional vortex structure of a synthetic jet

Nihon Kikai Gakkai ronbunshu, 2015
Synthetic jets are produced by periodic ejection and suction of fluid from an orifice induced by movement of a diaphragm inside a cavity, and a synthetic jet actuator is a useful tool for active flow control. The synthetic jet actuators are low operating

Precessing jets from a moving source and bright X-ray filaments in galaxy clusters

, 2005
We present hydrodynamical calculations carried out with the 3D yguazu-a code of a precessing jet model, which interacts with a plane parallel wind. This scenario describes an extragalactic jet, in which the jet source is in motion with respect to the ...

Experimental and numerical research of synthetic jet array

EPJ Web of Conferences, 2016
This paper describes the additional research of the synthetic jet array in a channel flow and continues the paper of authors Dančová, Trávníček and Vít, [1]. Numerical simulations support the experiments from [1] and the influence of the new slope of the

Acoustic aspects of synthetic jet generated by acoustic actuator

Journal of Low Frequency Noise, Vibration and Active Control, 2018
Thermal overstressing as a result of miniaturization is the foremost challenge for the next generation electronic devices. Shrinking size of electronic devices makes this problem even worse.

No-moving-part hybrid-synthetic jet actuator [PDF]

, 2006
In contrast to usual synthetic jets, the “hybrid-synthetic jets” of non-zero timemean nozzle mass flow rate are increasingly often considered for control of flow separation and/or transition to turbulence as well as heat and mass transfer.

Thermoacoustic cooling of loudspeaker-driven synthetic jet actuator

Case Studies in Thermal Engineering
To address the issue of declined cooling performance caused by the recirculation of hot jet flow into the cavity of conventional synthetic jet actuators, a loudspeaker-driven thermoacoustic-cooling synthetic jet actuator was developed by integrating a ...
