電気流体力学現象によるマイクロポンプのCFD解析

抄録

A phenomenon in which a flow occurs without external force is known as the electrohydrodynamics (EHD) phenomenon, when a high voltage is applied a dielectric liquid. A micropump using the EHD phenomenon has several advantages. For example, no mechanical parts are require, noise and vibrations are almost completely absent. The purpose of this study is to analyze the flow inside the micropump using the EHD phenomenon. Thus, two 4mm diameter circular tubes with electrodes on the inner wall were modeled as an EHD micropump. This study explored the effects on flow as analysis parameters to which the voltage was applied. As a result, it was found that a rotational movement occurred between the electrodes, and flow in one direction occurred from the anode to the cathode side.
