摘要 Present study investigates performance of synthetic jet actuator qualitatively. Its effectiveness of thickness of cavity, export area, working frequency and input voltage will be mainly studied by improved smoke flow visualization. The resonance frequency is also checked by the Helmholtz Resonance method and to well know interaction between the most effectiveness working frequency and cavity thickness. Experimental results indicated that higher input voltage makes higher smoke flow deflection angle and show the most obvious variation occurs at 200-400 Hz. Results also show the most efficiency working frequency is closed to resonance frequency of 400 Hz. The jet-to-wind velocity ratio of cross flow shows the same explanation. The ratio is inverse proportion to inflection level and proportion to penetration depth and turbulence intensity. Synthetic jet actuator with property cavity volume can cause higher exit velocity and increase velocity ratio R. It will increase penetration depth and cause higher turbulent intensity. Finally, the effect is more obvious and influence area is much larger.
