Design of synthetic jet actuator based on FSMA composite
An improved version of the membrane actuator has been designed and constructed based on our previous diaphragm actuator. It consists of ferromagnetic shape memory alloy composite (FSMA) diaphragm and an electromagnet system. The actuation mechanism of the membrane actuator is the hybrid mechanism that we proposed previously. The high momentum airflow will be produced by the oscillation of the c...
متن کاملNumerical Investigation of a Jet and Vortex Actuator (JaVA)
In the present study an active flow control actuator is studied numerically using the CFD package Fluent R ©. A two-dimensional setup is chosen which corresponds to a cut through the actual configuration that was studied experimentally by Lachowicz et al. [1] and called “Jet and Vortex Actuator” (JaVA) because of its ability to produce such completely different flow regimes when its actuation f...
متن کاملJet Snake Magnetohydrodynamic Equilibria
Magnetohydrodynamic (MHD) equilibrium states with a three-dimensional helical core that display the characteristics of a saturated ideal internal kink mode are computed to model snake structures that have been observed in the JET tokamak (Weller et al 1987 Phys. Rev. Lett. 59 2303). The equilibrium states are calculated with a peaked pressure profile and a weak to moderate reversed core magneti...
متن کاملA penalty model of synthetic micro-jet actuator with application to the control of wake flows
A simple model of synthetic (zero-net mass-flux) micro-jet is proposed and implemented in a large-eddy simulation spectral solver of the incompressible Navier-Stokes equations. Essentially, it is simply required to introduce a penalty like term in the momentum equation, with a variable penalty coefficient that culminates during the expulsion phase. Examples of applications are considered for th...
متن کاملInfluence of the energy dissipation rate in the discharge of a plasma synthetic jet actuator
A promising actuator for high-speed flow control, referred to as a Plasma Synthetic Jet (P.S.J), 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. The PSJ, which produces a synthetic jet with high exhaust velocities, no ...
