JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA18 Subject Category: JSS Inter-University Research PDF Responsible Representative: Seiichiro Morizawa, Lecturer, National Institute of Technology, Okinawa College Contact Information: Seiichiro Morizawa(morizawa@okinawa-ct.ac.jp) Members: Seiichiro Morizawa, Takashi Matsuno Abstract Recently, many kinds of research on unmanned aerial vehicles such as the Martian atmosphere and a high altitude one in the Earth’s stratosphere have been conducted actively. These environments become that the atmospheric density and temperature are much lower. Then, the flight・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA45 Subject Category: JSS Inter-University Research PDF Responsible Representative: Toshiharu Mizukaki, Professor, Tokai University Contact Information: Toshiharu Mizukaki, Professor, Tokai University(mzkk@tsc.u-tokai.ac.jp) Members: Toshiharu Mizukaki, Faming Wang Abstract Detonation waves are sel- propagated waves assisted by shock waves. Utilizing the detonation waves would rialize high-efficiency propulsion system. The pourpose of this project is to establish numerical analysy method for detonation characteristics obtained by experiments. Reference URL Please refer to https://www.mzkklab.com/ .・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21ETET12 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Takahashi(Aeronautical Technology Directorate) Contact Information: Yuya ohmichi (ohmichi.yuya@jaxa.jp) Members: Masato Harafuji Abstract Atmospheric entry capsules are known to be prone to dynamic instabilities during subsonic to transonic speed flight.It has also been suggested that low-frequency fluid phenomena may have an effect on the dynamic instability. In this study, in order to better understand wake phenomena, numerical fluid simulations were performed・・・<<read more>>
