Abstract
Two-dimensional compressible gas synthetic jet flow has the properties of viscous and unsteady. Based on the standard k-ε turbulent model, numerical simulation of the built compressible model was performed using dynamic mesh approach and the software Fluent. To optimize the performance of synthetic jet flow, its frequency characteristics, actuation frequency, amplitude and orifice parameters were analyzed. The results show that the simulated frequency characteristics of compressible synthetic jet is more consistent with theoretical ones, which demonstrates the rationality of the compressible gas model. It also indicates that there exist the optimum frequency and orifice width to reach the maximum velocity of given synthetic jet.
