Three-dimensional numerical simulation of discharge and flow related to airflow control using plasma actuator

[Added on] [Last modified on]

JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EACA16 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Tohoku University Contact Information: Naofumi Ohnishi(naohnishi@tohoku.ac.jp) Members: Rei Maeta, Naofumi Ohnishi, Shintaro Sato Abstract Plasma actuator has attracted attention as a fluid control device using dielectric barrier discharge. In the experimental study, it has been pointed out that the discharge has a spanwise distribution of the electrode and has a three-dimensional structure. The three-dimensional structure affects the induced・・・<<read more>>
