“…12,13) Because the Reynolds number (Re) in practical fluid machinery is often greater than 10 5 , it is necessary to improve technologies that can generate the larger thrust and induced flow velocity to enhance the aerodynamic control effect of DBD-PAs at high Re. For example, in terms of the components of DBD-PAs, studies related to dielectric materials, 14,15) serrated 16,17) and wire exposed electrodes, [18][19][20][21] tri-electrodes PAs (TED-PAs), 22,23) and DBD-PAs with discretized encapsulated electrode 24) have been conducted. On another front, various efforts have been made to reduce the amount of power supply for the future implementation of DBD-PAs in fluid machinery.…”

This study proposes a new driving method using dual power supplies to address a trade-off between power supply miniaturization and the high voltage output driving of a dielectric barrier discharge plasma actuator by simultaneously applying two AC voltages with opposite phases to the exposed and encapsulated electrodes. The performance of the proposed method was compared with that of two conventional driving methods that use a single power supply. The maximum peak-to-peak voltage with the single power supply was 23 kV, whereas that with the dual power supplies using a transformer with a lower output capability was 30 kV. At the same peak-to-peak voltage, the method using dual power supplies had intermediate time-averaged thrust and induced flow velocity among the three methods. This is attributed to the different discharge distributions at the edge of the exposed electrode, which are caused by the different electric field strengths for each method.

In this study, an experimental investigation of separation control using a dielectric barrier discharge plasma actuator was performed on an NACA0015 airfoil over a wide range of Reynolds numbers, angles of attack, and nondimensional burst frequencies. The range of the Reynolds number was based on a chord length ranging from 2.52 × 105 to 1.008 × 106. A plasma actuator was installed at the leading edge and driven by AC voltage. Burst mode (duty-cycle) actuation was applied, with the nondimensional burst frequency ranging between 0.1–30. The control authority was evaluated using the time-averaged distribution of the pressure coefficient Cp and the calculated value of the lift coefficient Cl. The baseline flow fields were classified into three types: (1) leading-edge separation; (2) trailing-edge separation; and (3) the hysteresis between (1) and (2). The results of the actuated cases show that the control trends clearly depend on the differences in the separation conditions. In leading-edge separation, actuation with a burst frequency of approximately F+= 0.5 creates a wide negative pressure region on the suction-side surface, leading to an increase in the lift coefficient. In trailing-edge separation, several actuations alter the position of turbulent separation.
