An advanced smoke-flow visualization system driven by high-pressure air was developed in this study.The main motivation was due to it is hard to visualize local flow field via traditional smoke-flow method in the past.The developed system processes highly practicality and convenience for user.Many devices were constructed on the system including regulator for fine tuning,smoke generator with remote controller and a funnel-shape device inside the chamber to converge output flow.Present system is applied to investigate performance of synthetic jet actuator qualitatively.Its effectiveness of thickness of cavity,export area,working frequency and input voltage will be mainly studied.Experimental results not only reveal the good useful for local flow field and indicate that higher input voltage makes higher smoke flow deflection angle and show the most obvious variation occurs when input frequency is 200-400 Hz.
