| Outline of Final Research Achievements |
A pump and an electrostatic oil filter that utilize electrohydrodynamic (EHD) phenomena are treated. The effects of electrode configuration of the EHD pump, filter configuration, and the physical properties of liquid on the performance of the EHD pump and electrostatic filter are investigated mainly by numerical simulation. It is shown that the optimal collector electrode configuration depends on the quantity of injected charges, and that a liquid with a lower viscosity yields a better pump performance. For the electrostatic oil filter, it is shown that particle trajectory simulation using EHD simulation results of the flow and electric fields can be helpful for a qualitative evaluation of filter performance. The numerical simulation method used in this investigation can be useful for predicting or evaluating the performance of EHD pump and charge injection type of electrostatic oil filter.
