Electrohydrodynamic (EHD) flow is an extremely efficient method of using high voltage to generate gas momentum, this approach has various strong points due to the system not having any mechanical component. There has been a lot of research about the locations of discharge points in EHD. However, only one-dimensional shifting has been identified using empirical relations. The Townsend relation between current and voltage shows stable corona discharge into gas. Also, momentum of EHD flow has a linear relationship with the square root of the current an can be expressed by an empirical equation. In this study, two-dimensional shifting of the discahrge point was carried out to uncover the relationship between discharge point and flow, which tackes account of not onlu axial but also lateral distances while using a pin to two cylinder configuration. As a result, the characteristics of EHD flow can be modeled and expressed as a function of a distance parameter. Therefore, an empirical relation of momentum with the experimental variables was derived.

电动流体（EHD）流动是一种使用高压产生气体动量的极其有效的方法，由于系统没有任何机械组件，因此这种方法具有很多优点。关于EHD中放电点的位置已有很多研究。但是，使用经验关系只能识别一维位移。电流和电压之间的Townsend关系显示出稳定的电晕放电成气体。同样，EHD流动的动量与电流的平方根具有线性关系，可以通过经验公式表示。在这项研究中，对不连续点进行了二维移动以揭示排出点与流量之间的关系，这说明了在使用销钉到两个圆柱体的配置时，轴向距离和横向距离都不是唯一的。结果，可以对EHD流量的特性进行建模并表示为距离参数的函数。因此，推导了动量与实验变量的经验关系。
