Abstract
There are two section in the main object of this thesis : First of all, I would like to discuss the advantage and shortage of Single Acting Synthetic Jet Actuator( SSJA) and Double Acting Synthetic Jet Actuator ( DSJA ) . The advantage of DSJA compared with SSJA is that the fluid sucked into the inner chamber is from diffuser but from the outer of the central nozzle. But the shortage is the velocity of the center of the vortex is slower. And also you can see the flow visualization of SSJA and DSJA. Here it shows how the fluid sucked into the inner chamber through the annual jet.
The second section is the discussion of the performance of DSJA. In this section, the velocity profiles in particular time and position will be fully discussed. And then we have the preliminary direction to optimize the performance of DSJA. It will provide a direction to design the micro structure of DSJA so that the application of DSJA will be increased enormously.
