An experimental characterisation study of a large-volume three-electrode Plasma Synthetic Jet Actuator (PSJA) is presented. A sequential discharge power supply system is used to activate the PSJA. Phase-locked planar Particle Image Velocimetry (PIV) and time-resolved Schlieren imaging are used to characterise the evolution of the induced flow field in quiescent flow conditions. The effect of orifice diameter is investigated. Results indicate three distinct features of the actuator-induced flow field. These are the initial shock waves, the high speed jet and vortex rings. Two types of shock waves with varied intensities, namely a strong shock wave and a weak shock wave, are issued from the orifice shortly after the ignition of the discharge.. Subsequently, emission of a high speed jet is observed, reaching velocities up to 130 m/s. Pronounced oscillation of the exit velocity is caused by the periodical behaviour of capacitive discharge, which also lead to the formation of vortex ring trains. Orifice diameter has no influence on the jet acceleration stage and the peak exit velocity. However, a large orifice diameter results in a rapid decline of exit velocity and thus a short jet duration time. Vortex ring propagation velocities are measured at peak values ranging from 55 m/s to 70 m/s. In the case of 3 mm orifice diameter, trajectory of the vortex ring severely deviates from the actuator axis of symmetry. The development of this asymmetry in the flow field is attributed to asymmetry in the electrode configuration.

“…Consequently, the simulation results of the temperature and the velocity are over-predicted. From the experiments of the active flow control with the PSJ, it can be found that the measured jet velocity is much lower than that of the numerical simulation (Haack et al, 2008;Caruana et al, 2009;Hardy et al, 2010). In the experiment, the actuator works continuously, but almost all the simulations of the PSJ are for a one-pulsed jet.…”

ABSTRACT:If the actuator of the plasma synthetic jet (PSJ) operates continuously under a high frequency, the performance of the actuator will become worse than it is in single pulse test. This is because the air in the cavity cannot fully recover to the original state before the next cycle starts. Therefore, the characteristics of the plasma synthetic jet during continuous operation, rather than during a single pulse, need to be studied carefully. In this paper, simulated flow fields of the continuously working PSJ are analyzed. It is found that the time-averaged results of the PSJ are self-similar, however, the instantaneous results are only self-similar when y is less than y 0.5 . Moreover, the effects of the dominant parameters, such as the maximum temperature, cavity shape and the operating frequency, on the performance of the PSJ actuator under stable operating condition are discussed. The maximum temperature is the most important parameter for the PSJ actuator. Actuator performance improves when the maximum temperature increases. In contrast, the frequency has little influence on performance, and the PSJ actuator is shown to perform well under a wide range of frequencies. This is more beneficial for active flow control compared with the synthetic jet actuator driven by the piezoelectric patch. The shape and the volume of the cavity can also influence the performance of the actuator. As the volume of the cavity becomes smaller, the duration of the spurt period is reduced.
