Abstract Details

2022, Master of Science, University of Toledo, Mechanical Engineering.
Inducing a high voltage (in the range of kV) between two proximate electrodes creates a spark, which is known as Corona Discharge. This discharge has the ability to induce a flow (ionic wind) in the medium with which it interacts. Such a flow is what is known as an Electrohydrodynamic flow (EHD), which has found many useful applications. One of its applications is mass-transport/pumping. Such an EHD pump offers many advantages, including high power efficiency and not requiring any mechanical moving parts to operate. Moreover, introducing water vapor into the stream of the ionic wind (i.e., between the two electrodes) allows driving water droplets into certain dielectric liquid. This in turn allows for the creation of emulsions. In order to create such emulsions, an understanding of the electrohydrodynamic (EHD) performance of the corona discharge is crucial. This can lead to better homogeneity and proper water droplet distribution, insuring higher quality and more stable emulsions. This study investigates the pumping performance of an in-house built corona discharge setup for inducing circular motion in the fluid. Silicone oils of different kinematic viscosities are used as the EHD fluid. The EHD performance/fluid characteristics are studied experimentally using particle image velocimetry (PIV) under different types of current (DC and AC). Within DC, a voltage parametric study is performed to investigate the effect of different potential drops on the flow. On the other hand, a frequency parametric study is carried out to highlight the effect of such parameters on the flow under AC conditions.
