“…Figure 7 gives the time-averaged stream-wise velocity along the centerline of PSJ with different actuation frequencies. It can be seen that in the whole range of the actuation frequency considered in the present study, the time-averaged stream-wise velocity along the centerline of PSJ has reached its maximum value(about 0.6 m s 1 ) at the position about x=6 mm, which is very similar to the steady actuation case [13]. At the rest stream-wise locations along the centerline, the curves of stream-wise velocity of PSJ overlap with each other.…”

“…Zhang and Wang [18] also used the standard k- turbulent model to simulate the synthetic jet in a quiescent environment, and the results matched quite well with the benchmark experimental data of NASA Langley Research Center [19]. The details of the governing equations and numerical method can be found in the author's previous work [13].…”

“…The right and left edge outflow boundary is 10w from the centerline and the upper edge outflow boundary is 20w from the wall. The grid dimension of the plasma area is 70×50 [7], and the total node number of the computational area is 134000 [13]. More details of the grid can be found in author's previous work [13].…”

“…Most recently, Liu et al [13] investigated the flow characteristics of PSJ with unsteady actuation by numerical simulation. The results indicated that the time-averaged flow field of unsteady PSJ is quite similar to those of the steady PSJ, the traditional synthetic jet and the plane jet.…”

The flow induced by plasma synthetic jet actuator was simulated through solving the Reynolds-averaged Navier-Stokes equations augmented by body force phenomenological plasma model. The effect of actuation frequency on the plasma synthetic jet was examined by case study. The numerical results present that with the actuation frequency increasing, the stream-wise distance of the adjacent vortex pairs induced by the actuator decreases monotonically, which is the same as the situation of the velocity fluctuations field caused by the vortex pairs. When the actuation frequency is 60 Hz, the vortex pairs formed during the adjacent actuation periods merge together quickly, and the flow structure in the downstream region is more close to that of the steady case. The actuation frequency has no visible influence on the time-averaged flow field of plasma synthetic jet. However, when the actuation frequency is relatively low (f<40 Hz), the momentum flux close to the actuator increases with the actuation frequency increasing, which is contrary to the situation in the far field from the wall. plasma actuator, synthetic jet, numerical simulation, actuation frequency Citation: Zhang P F, Dai C F, Liu A B, et al.

“…This DBD actuator is also named plasma synthetic jet actuator (PSJA) [10,11] . Despite the great performance improvement of DBD actuator, its induced flow velocity is still low at present, usually less than 10m/s [12,13] .This deficit restricts its application in supersonic flow control.…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link Abstract:The plasma synthetic jet actuator (PSJA) is a flow control device capable of generating high speed pulsed jet. However, the performance of conventional PSJA is restricted by low discharge efficiency and small control area, because one power supply only drives one electrode couple. The present work is to propose a new concept of multichannel discharge plasma synthetic jet actuator (MD-PSJA), which is driven by single power supply. The new MD-PSJA has two types, namely the multi-electrode PSJA and the multi-PSJA array. These two types of MD-PSJA are examined experimentally. The multi-electrode PSJA containing 11-electrode PSJA is first studied. Comparison with standard 2-electrode PSJA reveals that the discharge efficiency and jet velocity increase 200% and 47% respectively under the same input energy and discharge voltage. The multi-PSJA array is later evaluated. One power supply is found to be able to drive an array of 12 PSJAs, resulting in 6 times affected area and 64% jet velocity of a conventional PSJA. The proposed MD-PSJA is finally concluded an improved active flow control actuator in high speed applications.
