Application of distributed micro plasma actuators

[Added on] [Last modified on]

JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA47 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: Rikiya Hata, Nana Hasegawa, Masahiro Kanazaki, Seiichiro Morizawa, Takashi Matsuno, 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 a surface by using a large・・・<<read more>>

Nonlinear interactions of Rossby waves and large-scale zonal flow formation in two-dimensional turbulence on a rotating sphere.

[Added on] [Last modified on]

JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA46 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 mechanism・・・<<read more>>

JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA45 Subject Category: JSS Inter-University Research PDF Responsible Representative: Toshiharu Mizukaki, Professor, Tokai University Contact Information: Toshiharu Mizukaki, Professor, Tokai University(mzkk@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>>

Numerical Study on Propeller Slipstream Effects on Objects at Low Reynolds Number

[Added on] [Last modified on]

JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA43 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate professor, Yokohama National University Contact Information: Keiichi Kitamura(kitamura@ynu.ac.jp) Members: Yoshikatsu Furusawa, Keiichi Kitamura, Keita Suzuki, Shunya Sakatsume Abstract As a new form of a Mars exploration vehicle, research and development of a propeller-driven Mars airplane are progressing. Because the low atmospheric density on Mars causes the flow around the Mars airplane at low Reynolds numbers, the flow field・・・<<read more>>
