Abstract

This chapter deals with the preliminary design of a synthetic jet generator. The effect of the synthetic jet strongly depends on its frequency, which should correspond to the natural vortex shedding frequency of the flow. This frequency can be found using the Strouhal number (nondimensional frequency). The design of a synthetic jet generator must take into account the vortex shedding frequency and acoustic properties of generator. The lumped element model (LEM), which is based on an analogy between electrical and acoustic domains, may be applied in the preliminary design of a synthetic jet generator. LEM is particularly useful in determining the amplitude-frequency characteristic (output velocity x frequency) of the synthetic jet actuator.
