This paper presents a generalized non-dimensional theoretical formulation with boundary conditions to analyze the EHD flow within the conducting and non-conducting channels. The substantial effect of normal and tangential components of electric field on fluid flow within the channel is presented through simulation results based on the non-dimensional parameters of strength, penetration, and repulsion of electric forces. The simulation results reveal that the normal component of induced electric field transits the flow regime within surfaces of a channel. The tangential component of applied electric field increases the thickness of viscous boundary layer, leading to skewed velocity profiles.

本文提出了一种具有边界条件的广义无量纲理论公式，以分析导电和非导电通道内的 EHD 流动。通过基于电力的强度、穿透和排斥等无量纲参数的仿真结果，展示了电场的法向分量和切向分量对通道内流体流动的实质性影响。模拟结果表明，感应电场的法向分量在通道表面内穿过流态。外加电场的切向分量增加了粘性边界层的厚度，导致速度分布偏斜。
