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>>
