Abstract

The structure of electrohydrodynamic (EHD) flows in a variable electric field has been investigated based on computer simulation of EHD flows in a needle–plane electrode system. The characteristic frequency interval of a feed sine-wave voltage with an amplitude of 5 kV has been considered. Changes in the charge and velocity structures of EHD flows are described, and the characteristic features of the flows versus feed voltage frequency are presented. The periodicity of such EHD flows is demonstrated.

变场中注入型电动流体流动的结构

摘要

基于在针-平面电极系统中的EHD流动的计算机模拟，研究了在可变电场中的电动流体（EHD）流动的结构。已经考虑了幅度为5 kV的正弦波电压的特征频率间隔。描述了EHD液流的电荷和速度结构的变化，并给出了液流与进给电压频率之间的特性关系。演示了此类EHD流的周期性。
