• Summary form only given. A synthetic jet actuator (SJA) with different exits and the piezoelectric (PZT) vibrator in clamped and simply supported edge conditions is modeled using lumped elements. The equivalent circuit of the SJA and the frequency-response function of the circuit are established to analyze the frequency behavior of the SJA. Results show that the PZT vibrator parameters, the actuator cavity volume and exit size, and the medium affect the frequency behavior of the SJA. The curve of the delay phase angle of the synthetic jet shows the synthetic jet velocity will be in-phase with the PZT vibrator when the actuator driven frequency is lower than the response frequency of the actuator cavity-exit system, and will be out-phase when the actuator driven frequency is higher than the response frequency of the actuator cavity-exit system. This directs us to put forward novel high performance dual synthetic jets actuators.
