Electromechanics of droplet under electric field: basics, simulation and experiments [12月13日（火）九州大学]
2022/11/15
【科目種別】電気エネルギー講座Ⅱ（英語科目）
■講師：Boonchai Techaumnat 教授(Chulalongkorn University, Thailand)
■演題：Electromechanics of droplet under electric field: basics, simulation and experiments
■日時：令和4年12月13日（火）16：00～ 17：30
■場所：Zoomによるオンライン配信
■主催：大学間連携共同教育プログラム
■協賛：九州パワーアカデミー
■申込/お問合せ：九州大学 大庭 e-mail:ohba@ees.kyushu-u.ac.jp
■概要
• Droplets play important roles in a variety of electric applications.
• For example, aqueous drops on an insulating surface or in insulating oil have significant effects on the system performance.
• Unlike solid particles whose behavior is predictable based on their charging condition and electric field, aqueous droplets may change their shape readily under electric field.
• Such characteristic complicates the electromechanical behavior of droplets.
• Deformation, breakup and coalescence of droplets can take place and are influenced by the existence of electric field.
• The following topics will be presented in the talk:
(i) Fundamentals of electromechanical interaction between electric field and the droplet,
(ii) Numerical analysis of droplet stability under electric field,
(iii) Simulation of drop dynamics to investigate droplet deformation and coalescence.
(iv) Experimental observations of charge and uncharged droplet behavior under electric field.
