dcterms:description
The paper deals with preliminary design of the synthetic jet generator. The effect of the synthetic jet to the flow field strongly depends on frequency of the synthetic jet. Frequency of the synthetic jet should correspond to the natural vortex shading frequency of the flow behind the body. This frequency can be found using Strouhal number (nondimensional frequency). The design of generator of the synthetic jet must be done with respect to the vortex shading frequency of the flow and with respect to the acoustics properties of the synthetic jet generator. Lumped Element Model (LEM), which is based on analogy between electrical and acoustic domain, for preliminary design of the synthetic jet generator can be used. Acoustics properties of the synthetic jet generator are possible to be defined applying of electro-acoustic theory to the individual part (cavity, output orifice, membrane) of the synthetic jet generator. Amplitude-frequency characteristic (output velocity x frequency) of the synthetic jet actuator is obtained from LEM. The paper deals with preliminary design of the synthetic jet generator.
