Abstract
Synthetic jet flow is created by the compression effect in actuator's cavity caused by vibration of piezoelectric diaphragm, whose mechanism is similar to a micro compressor. To get the relationship between the performance of synthetic jet flow and the actuator parameters, the compressibility of gas has been considered and the correlation function reflecting that relationship was obtained by theoretical analysis. The vibration of piezoelectric diaphragm was simulated using moving boundary condition and numerical simulation was implemented under compressible gas model with moving boundary. It is shown that the simulation results are comparable to the results of experiment and theoretical analysis.
