Boundary Condition Effects on Piezo-Synthetic Jets

چکیده
Three circular piezoelectric actuators: Bimorph, Thunder, and Radial Field Diaphragm (RFD) function as oscillating diaphragms within a cavity to produce a zero net mass flux air jet. To characterize each diaphragm, displacement response and vibrational characteristics with varying mechanical and electrical boundary conditions were investigated using a saw tooth waveform at 5 Hz. Clamping pressure around the perimeter of each actuator and gain dampening feedback of the amplifier were varied to statistically evaluate their significance on displacement. The results showed that displacement variations due to clamping pressure for all actuators are significant, with those for RFD at the highest

متن کاملInteraction of Synthetic Jets with Laminar and Turbulent Boundary Layers
The interaction between circular synthetic jets and flat-plate laminar/turbulent boundary layers is investigated using CFD simulations in this study. For turbulent boundary layer simulations, large eddy simulation (LES) is applied so as to obtain more accurate flow details. The simulation results are validated using both existing experimental data and numerical results obtained from other resea...
متن کاملPressure Loading of Piezo Composite Unimorphs
Over the past decade synthetic jets have emerged as a promising means of active flow control. They have the ability to introduce small amounts of energy locally to achieve non-local changes in the flow field. These devices have the potential of saving millions of dollars by increasing the efficiency and simplifying fluid related systems. A synthetic jet actuator consists of a cavity with an osc...
متن کاملSimulation of slot and round synthetic jets in the context of boundary-layer separation control.
Synthetic jets--also referred to as mass-less jets--offer the potential of effective, on-demand, fluid-based control of separating boundary layers on highly loaded aerodynamic surfaces, without the need for a mass source. However, the control authority that may optimally be derived from such jets, and any generality of the underlying flow physics are obscured by the wide range of geometric and ...
متن کاملNumerical Simulation of Free Surface in the Case of Plane Turbulent Wall Jets in Shallow Tailwater
Wall-jet flow is an important flow field in hydraulic engineering, and its applications include flow from the bottom outlet of dams and sluice gates. In this paper, the plane turbulent wall jet in shallow tailwater is simulated by solving the Reynolds Averaged Navier-Stokes equations using the standard turbulence closure model. This study aims to explore the ability of a time splitting method ...
