JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA16 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Tohoku University Contact Information: Naofumi Ohnishi(naohnishi@tohoku.ac.jp) Members: 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 flow distribution・・・<<read more>>

JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA12 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Tomohiro Mamashita(mamashita-tomohiro-nj@ynu.jp) Members: Yuka Hara, Hibiki Kumai, Keiichi Kitamura, Tomohiro Mamashita, Kouya Nakahara Abstract Reusable launch vehicles are studied to reduce space transportation costs. Reusable rockets perform return flights that conventional expendable rockets do not experience. We worked to clarify the aerodynamic characteristics of a vehicle during the return phase using numerical・・・<<read more>>
