JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EACA63 Subject Category: JSS Inter-University Research PDF Responsible Representative: Ko Ogasawara, Tokyo Univercity of Science Contact Information: Kohei Koyama(7520040@ed.tus.ac.jp) Members: Koyo Ando, Kohei Koyama, Ko Ogasawara Abstract The aim of this study is to simulate aerodynamic heating around a vehicle flying at hypersonic speeds in the atmosphere and to identify flight conditions and vehicle designs that help reduce heat flux to the surface. The expected outcome is a reduction in・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EACA64 Subject Category: JSS Inter-University Research PDF Responsible Representative: Nobuyuki Sawado, Professor, Tokyo University of Science Contact Information: Nobuyuki Sawado(sawadoph@rs.tus.ac.jp) Members: Nobuyuki Sawado, Yuta Suzuki, Kohei Shimasaki Abstract Mathematical models that describe phenomena of planetary atmosphere sometimes are closely related to nonlinear partial differential equation (PDE) in (quasi-)integrable systems. We try to give a formal mathematical characterization of the relationship between various quasi-integrable PDEs and these models of planetary atmospheres.・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EACA65 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Department of Aerospace Engineering, Tohoku University Contact Information: Yuto Nakamura(yuto.nakamura.t4@dc.tohoku.ac.jp) Members: Yuto Nakamura, Naofumi Ohnishi Abstract On many fluid systems, such as aircraft and turbines, transition phenomena occur in the wake flow in which the vortex structure drasticaly changes. Since such transitions are accompanied by significant changes in flow frequency and hydrodynamic forces acting on the objects, it・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EACA66 Subject Category: JSS Inter-University Research PDF Responsible Representative: Hiroshi Kimura, Professor, Micro/Nano technical center, Tokai University Contact Information: Yuki Kawamoto(kawamoto.yuki.u@tokai.ac.jp) Members: Katsuki Hirai, Yuki Kawamoto, Hiroshi Kimura Abstract Heat pipes, which transport heat through the flow of a working fluid that undergoes a phase change due to evaporation and condensation, are used not only in familiar electronic devices but also in devices that are expected to be used in・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EAE30300 Subject Category: Space Exploration PDF Responsible Representative: Norihito Tsuji, Human Spaceflight Technology Directorate, Lunar Gateway Habitation Project Team Contact Information: Ryosuke Takahashi(takahashi.ryohsuke@jaxa.jp) Members: Kenji Kano, Masaru Saijo, Daisuke Sugawara, Ryosuke Takahashi Abstract "Gateway" is the manned base to be constructed in lunar orbit as a relay base for sustained lunar surface exploration activities, in the international space exploration plan "Artemis Project". Space Agencies participating in the ISS project are・・・<<read more>>
