Numerical calculations and optimal design were conducted from the perspectives of・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EACA60 Subject Category: JSS Inter-University Research PDF Responsible Representative: Koji Miyaji, Professor, Yokohma National University Contact Information: Koji Miyaji(miyaji@ynu.ac.jp) Members: Kazuki Hyodo, Koji Miyaji, Kenichiro Takayanagi Abstract The static and dynamic stability of high-speed flying objects are evaluated by CFD. We Actual analysis target is the High-Mach Integrated Control experiment (HIMICO), a hypersonic integrated control experiment being jointly researched and developed by JAXA and several universities. We compare CFD analysis,・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24EACA61 Subject Category: JSS Inter-University Research PDF Responsible Representative: Kazuto Kuzuu, Professor, Department of Mechanical Engineering, Tokai University Contact Information: Kazuto Kuzuu, Tokai University(kuzuu@tsc.u-tokai.ac.jp) Members: Kazuto Kuzuu, Masato Ogawa Abstract When there is a flow path with a narrow diameter and temperature gradient in a gas-filled duct, acoustic vibration may occur thereby. This phenomenon is known as a thermoacoustic phenomenon, and the generated acoustic field may be accompanied by a・・・<<read more>>
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>>
