EHD現象を利用した円管内流れの数値シミュレーション

抄録

This study involves the application of EHD phenomena to a pump. EHD phenomena occur when a high voltage is applied to a dielectric liquid, causing the liquid to flow. If the phenomena are used, the liquid's flow can be controlled by arranging electrodes within the liquid and applying a voltage, thus greatly reducing the overall number of parts the pump requires, especially sliding parts, such as impellers. In turn, this makes it possible to reduce the size and weight of the pump. Specifically, the phenomena are created inside the pump by applying high voltage to an electrode installed within a circular tube, which generates a unidirectional flow within the liquid. The purpose of this study is to verify the effects of EHD phenomena by calculating the velocity and pressure distribution of a liquid inside a cylindrical tube, using computational fluid dynamics.
