電力輔助霧化與一般霧化方式之區別乃在於其透過使工作流體帶電的方式造成電荷與電場及其他電荷之間的庫侖力參與霧化過程，而非單純透過傳統力學或聲學的方式來操縱霧化之進行。其擁有達到應用力學與聲學難以達到的霧化效果之潛力。唯霧化方式學理上仍遵守一般霧化的大原則——也就透過特定的方式輔助造成液柱或液膜之不穩，進而導致其破碎( breakup )而完成霧化。
本研究的目標主要在於以酒精、水製成的混合溶液之模擬液體實驗建立資料庫，觀察電力輔助霧化模式之演變並分析其中錐狀噴流現象區間邊界隨操作噴口距離、工作液體基本參數( 介電常數、電導率、表面張力等 )參數改變而演變之趨勢。目前已經進行的部分計有各模式定性觀察與錐狀噴流模式現象區間邊界演變趨勢觀測、以及於間邊界上液錐的特徵幾何量測。研究中發現，在模式演變方面，不同工作流體模式重疊部分轉化過程皆按照(1)滴落，(2)紡錘，(3)微滴，(4)錐狀噴流，(5)複紡錘依序形成；錐狀噴流現象區間邊界方面則發現其於能量分配與受力上皆具有獨特性：邊界隨流量之變化依能量分布型態可區分為三區，分別為(△KE/△SE) = 10^-2~10^-1、10^-1~10^-0、10^-0~10¹；模式受力上也可將之區分作表面張力與重力作用可忽略之特殊型態，由分析得等效庫侖力與重力之比值範圍為1 < r < 10²。模式存在的區間範圍大小變化則各操控參數對其有不同趨勢之影響。

The electro-assisted atomization distinguishes itself from conventional atomization method by introducing the coulomb force and having extraordinary performance over conventional ones especially on droplet-size and monodispersity. Despite of these it still falls in the regime of “atomization”, for the sake that in the whole process disturbances is induced and amplified to generate liquid film or jet breakup phenomenon, just as in the conventional cases.
This research focused on the establishing of EHDA data base, observing the various modes and transitions between each, and, analyzing the behavior and limits in cone-jet phenomena. By taking ethanol liquid solution as working fluid in series of EHDA experiments, qualitative observations of modes, transitions between them, and tendency of potential change on the boundary of cone-jet phenomena region have been obtained. Observations show that mode changes in the same way, from dripping to spindle, microdripping, cone-jet, multi-cone-jet, multispindle no matter what degree of alcohol volumetric concentration the solution got. And on the other hand the uniqueness of cone-jet phenomena has been found from both energy and reacting force points of view: the tendency of boundary electric potential change vs. flow rate is found being able to be split into three main sub-tendency, classified as (△KE/△SE) = 10^-2~10^-1、10^-1~10^-0、10^-0~10¹; and reacting force type on the working fluid can be described as one which surface tension force and gravity being negligible, ratio between effective coulomb force and gravity force falls in the region of 1 < r <10².
