JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EACA63 Subject Category: JSS Inter-University Research PDF Responsible Representative: Ko Ogasawara, Tokyo Univercity of Science Contact Information: Atsuki Yoshida(7525570@ed.tus.ac.jp) Members: Kohei Koyama, Ko Ogasawara, Jinto Suzuki, Kento Tashiro, Atsuki Yoshida 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・・・<<read more>>
JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EACA64 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, Yuichiro Shimazaki, Yuta Suzuki Abstract Mathematical models that describe phenomena of planetary atmosphere and related subjects enjoying the chaotic property 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・・・<<read more>>
JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EACA67 Subject Category: JSS Inter-University Research PDF Responsible Representative: Kiwamu Yoshii, Assistant Professor, Tokyo University of Science Contact Information: Kiwamu Yoshii(qyoshii@rs.tus.ac.jp) Members: Sota Arakawa, Kiwamu Yoshii Abstract This study aims to clarify the physics that determines the efficiency of orbital deflection of small bodies by hypervelocity impact. In particular, we focus on the initial porosity of the target bodys surface layer, the compaction behavior of pores, and the shear strength・・・<<read more>>
