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>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA41 Subject Category: JSS Inter-University Research PDF Responsible Representative: Makoto Sato, Associate Professor, Kogakuin University Contact Information: Makoto Sato, Kogakuin University(msato@cc.kogakuin.ac.jp) Members: Makoto Sato, Kota Yoshikawa Abstract A Mars helicopter “HAMILTON” has been developed by JAXA, Tokyo Metropolitan University and Kogakuin University. Since the atomospheric density on Mars is about 1/100, the sound of speed is about 3/4 compared with those on Earth, we need to develop the high perfmance・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA43 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate professor, Yokohama National University Contact Information: Yoshikatsu Furusawa(furusawa-yoshikatsu-vz@ynu.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>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA39 Subject Category: JSS Inter-University Research PDF Responsible Representative: Masanobu Inubushi, Associate Professor, Tokyo University of Science Contact Information: Masanobu Inubushi(inubushi@rs.tus.ac.jp) Members: Masanobu Inubushi, Satoshi Matsumoto, Naoki Sakata, Tomoki Sugihara, Hiroto Tanaka Abstract Turbulence models play essential roles in aerospace science and technology, such as flows around aircraft and of planetary atmospheres. They are rapidly empowered by machine learning methods (Duraisamy, Iaccarino, and Xiao, 2019) and will be a crucial・・・<<read more>>
