MEASUREMENT OF AIR FLOW VELOCITIES IN MICROSIZED IONIC WIND PUMPS USING PARTICLE IMAGE VELOCEMITRY

The knowledge of the flow fields inside of microsized ionic wind pumps has become more important as the need for smaller and more efficient heat removal devices has increased. Understanding these flow fields will help optimize the ionic wind pumps. Non-intrusive microscale particle image velocemity (PIV) utilizing a microscopic objective lens is used to obtain the flow field inside of the ionic wind pump. Voltages ranging from 1700 to 2000 V are used, as well as seeded flow rates of 1.5 and 1.84 L/min. Computational models are used to qualitatively verify the flow fields. The effects of voltage and seed flow rate are also compared. The computational and PIV flow fields are shown to be very similar. It is shown that as the voltage applied to the ionic wind pump increased, the maximum velocity inside of the ionic wind pump increased, ranging from 1.71 m/s to 3.19 m/s. The average mass flow rate inside of the device also increased as the voltage increased, ranging from .0009 g/s to .0019 g/s. It is also shown that the seed flow rate has little effect on the PIV flow field obtained.
