摘要

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.
