PIV Measurements of Electrohydrodynamic Flow from Injection Charges on Free Surface of Dielectric Liquid

Abstract

We have been researched on the velocity field measurements of EHD flow. Thus paper describes PIV measurements of the EHD flow that is created by injection charge motion on free surface of dielectric liquid. Some experimental results show steady EHD flow with an interesting vortex for lugh resistivity dielectric liquid such as silicone oil. The velocity fields of the EHD flow are successfully obtained by means of the flow visualization technique and the PIV technique.
