摘要

研制了一种新型非侵入式两相EHD泵“AW型EHD泵”，其电极系统由气相电晕丝电极和气液界面倾斜板电极组成。研究了两相EHD泵的时间平均泵送流量、时间平均电流-电压特性、液膜厚度和工作流体在平板电极表面的流速等基本特性。从无量纲参数的角度详细讨论了放电极性对电流传导和电流体动力诱导液体流动的影响。

Polarity effect on electrical current conduction and electrohydrodynamically induced fluid flow in a AW type EHD pump

A new type of nonintrusive two-phase EHD pump "AW type EHD pump" was developed, where the electrode system consists of a corona wire electrode in gas-phase and a plate electrode inclined in a gas-liquid interface. The fundamental characteristics of the two-phase EHD pump such as time averaged pumping flow rate, time averaged current-voltage characteristics, liquid film thickness and flow velocity of working fluid at the plate electrode surface etc. were investigated. The effect of discharge polarity on electrical current conduction and electrohydrodynamically induced liquid flow is discussed in detail in the terms of a dimensionless parameter.
