摘要:
近年来,电流体力学(Electryhodrodynamics,又称 EHD)已成功地应用于液态离子源技术。但由于缺乏相应的电流体力学分析方法,尤其是能够解决工程实际问题的数值分析方法,因而不能对电致流体运动给予直观的、定量的描述。本文以流体力学运动方程为基础,讨论了电流体力学的方程体系。重点分析了电场力与流体表面张力对流体运动的影响,并应用标志网格法(Marker and Cell)建立了电致流体运动的计算机模拟程序。计算了圆管流体在外电场与表面张力作用下的流动情况。计算结果与文献[9]的实验观察结果一致。
Abstract:
Electrohydrodynamics(EHD)has been successfully applied to liquid ion source techniques in recent years.However,because there are few suitable analysis methods in EHD,especially the numerical methods,used to solve engineering problems,one can not present a visual and quantitative description for electrically driven motion of a fluid.In this paper,an equation system of EHD based on the fluid motion equations is discussed.Emphasis is put on the effects of electrical force and surface tension upon the fluid motion. The Marker and Cell method is extensively used to set up a computational simulation program of electrically driven motion of fluid.With the help of the program,a cylindrical fluid under the influences of electrical field and surface tension has been calculated.The result is well agreement with the experimental observation.
