Synthetic jet actuator with two opposite diaphragms [PDF]

Mechanics and Mechanical Engineering, 2020
Abstract The synthetic jet actuators are one of the most investigated types of actuators used in heat transfer and active flow control. The energetic efficiency of actuators is a key parameter determining the possibility of device use. The actuators with two or more diaphragms have higher efficiency than the actuators with only one.

Computational and Experimental Study of Heat Transfer on the heat sink with an impinging synthetic jet under Various Excitation Wave

Case Studies in Thermal Engineering, 2021
This work presents an investigation of an impinging synthetic jet produced by a continuous movement of an oscillating piezoelectric membrane in a synthetic jet actuator (SJA). The jet stream blows from the top of the heat sink attached to an electrically

Time-step coupling for hybrid simulations of multiscale flows [PDF]

, 2013
A new method is presented for the exploitation of time-scale separation in hybrid continuum-molecular models of multiscale flows. Our method is a generalisation of existing approaches, and is evaluated in terms of computational efficiency and physical ...

Investigation of synthetic jet magnetohydrodynamic actuator

Journal of Physics: Conference Series, 2016
Current paper is devoted to study new plasma actuator type—plasma synthetic jet actuator, based on the magnetohydrodynamic flow acceleration. Gas is accelerated inside the planar channel by the pulsed arc with current ~ 300 A, moving in the external magnetic field of 1.2 T. The channel is opened at both sides.
