This paper aims to study the effect of different geometrical and electrical parameters, including the voltage, frequency, dielectric thickness, gap width between electrodes, length of electrodes, number of electrodes, and shapes of electrodes, on the induced velocity by the Dielectric Barrier Discharge (DBD) plasma actuators in quiescent air. In addition, the effect of the course of induced velocity evolution in the downstream of actuators has been investigated for different geometries. The streamwise velocity was obtained through the total and static pressure measurement using silicon tubes. The model is a flat plate equipped with a DBD plasma actuator. These experiments were performed for the peak-to-peak voltage range between 8 and 15 kV, and two values of frequency are equivalent to 5 and 10 kHz. The results showed that the multilinear DBD plasma actuator has a maximal induced velocity in the same voltage and frequency as of a single DBD plasma actuator. Evaluation of the induced velocity along the streamwise direction for multilinear, serpentine, and horseshoe actuators showed that these actuators had more than one induced velocity peak.
