    Abstract
  • Numerical simulations are performed to investigate the effects of gas compressibility on the synthetic jet flow. A slot synthetic jet and a circular orifice synthetic jet are simulated assuming 2D and axis-symmetric behavior. The velocity of orifice, frequency response and the compressibility are studied through simulation. The numerical results are validated against existing experimental and analytical data, and good agreement are obtained. Gas compressibility effects on the synthetic jet flow are discussed. In conclusion, for the two kinds of different synthetic jets studied in this paper, the critical values of Mach number are 0.082 and 0.033.
