JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA49 Subject Category: JSS Inter-University Research PDF Responsible Representative: Taku Nonomura, Associate Professor, Tohoku University Contact Information: Taku Nonomura, Tohoku University(nonomura@tohoku.ac.jp) Members: Taku Nonomura, Takayuki Nagata Abstract Large-eddy simulations (LES) of the compressible flow around the plate with Reynolds number O (10^3) -O (10^4) were performed. The compressibility effects on the laminar flow separation bubble formed around the leading edge of the flat plate and turbulent transition were investigated. The・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA47 Subject Category: JSS Inter-University Research PDF Responsible Representative: Takashi Matsuno, Associate Professor, Tottori University Contact Information: Takashi Matsuno(matsuno@tottori-u.ac.jp) Members: Takeo Hoshino, Rikiya Hata, Masahiro Kanazaki, Daisuke Kikuchi, Yuki Kishi, Seiichiro Morizawa, Takashi Matsuno, Takuya Nankaku, Taisei Nishimura Abstract Plasma actuators (PAs) are flow control devices that use discharged plasma to generate wall jets from smooth surfaces. In recent years, a method of generating a distribution of body force on・・・<<read more>>

JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA45 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 For fundamental study on propagation of detonation waves inside rotating detonatio engines, fundamental numerical analysis using CHARIOT was done. In FY2022, 2D numerical analysis on propagation of detonation waves inside a rotating detonation engine with C2H4/O2 and H2/AIR mixture gases have been calucurated.・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA46 Subject Category: JSS Inter-University Research PDF Responsible Representative: Kiori Obuse, associate professor, Okayama University Contact Information: Kiori Obuse(obuse@okayama-u.ac.jp) Members: Yusuke Hagimori, Kiori Obuse Abstract Two-dimensional barotropic model on a rotating sphere is one of the simplest mathematical models describing the dynamics of planetary atmospheres. The two -dimensional turbulence shows the spontaneous formation of large-scale zonal flows similar to those seen on giant gas planets such as Jupiter. However, this・・・<<read more>>
