要約(英語): I have studied the relationship between electrical conduction and the EHD motion induced in mineral oil, between metal electrodes when their polarities are reversed. This paper describes the results of the three-dimensional numerical calculations of electrical conduction and the EHD motion induced in mineral oil by the reversal of electrode polarities at the time of peak current. The calculation employs Euler's equation, the Navier-Stokes equation, Poisson's equation, and the equation of charge continuity. The main results are as follows: (1) The calculation results of the current waveform are in agreement with the experimental results, with the exception of the time range that has large effects due to charging and absorption currents. (2) The current waveform is related to the time dependence of the current induced by the flow. (3) The distribution of space charge density and flow velocity between electrodes are visualized by the three-dimensional diagram of contour surfaces and the three-dimensional vector diagram.
