Recent Developments on Synthetic Jets (Review Paper)

Abstract

<p>Synthetic jet is a form of pulsatile jet where the flow is synthesised from the ambient air and it does not need any external source as the flow is induced from the fluid existing around orifice/nozzle. This property makes synthetic jet unique compared to pulsatile and continuous jets. Recently, the synthetic jet is being widely used for flow control, mixing and heat transfer enhancement in aerospace applications. Focused on reviewing the recent developments on synthetic jet characterization and their applications resulting from the development of advanced diagnosing tools.</p>

Influence of Synthetic Jets on Multiscale Features in Wall-Bounded Turbulence

“…Actuators 2022, 11, x FOR PEER REVIEW 5 of 17 (7) The proportion of cumulative energy is defined as:…”

“…Fortunately, the synthetic jet actuator (SJA) has the ability to generate local blowing and suction without additional air supply. This facilitates interaction with vorticity structures in the TBL [7], which has tremendous potential.…”

Effect of geometric parameters on synthetic jet: A review

“…A few reviews on various topics with regard to SJAs are available. These topics include the fundamental aspects [6], [8], [36], [37],…”

“…Nevertheless, a piezoelectric driver is the most favourable mechanism for flow control and thermal management applications due to its short response time, light weight and highly efficient performance [6].…”

“…Next, the separated shear layer will roll up to form a vortex ring. Due to the periodic oscillation of the diaphragm, a train of vortex rings will be produced, which will propagate away from the orifice in response to the self-induced velocity [6].…”
