JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22ECWU07 Subject Category: Cooperative Graduate School System PDF Responsible Representative: Sadatake Tomioka, Associate Principal Researcher, Research and Development Directorate, 4th Unit. Contact Information: Sadatake Tomioka (RInsertHereD directorate, 4th Research Unit)(tomioka.sadatake@jaxa.jp) Members: Sadatake Tomioka, Hironobu Nishiguchi, Kota Kubosaki, Hattori, Ryota Ito, Shota Hatta Abstract Fully reusable launch vehicle will reduce the transportation cost and increase the space launch demands. Introduction of airbreathing engine will afford system weigth penalty necessary to realise・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22ECWU03 Subject Category: Cooperative Graduate School System PDF Responsible Representative: Yasuhiro Mizobuchi, Aviation Technology Directorate, Aircraft Lifecycle Innovation Hub Contact Information: Hiroki Tsujimura (Waseda University)(hiroki-tsujimura@toki.waseda.jp) Members: Hiroki Tsujimura Abstract In this project, we study the particle-grid hybrid analysis method, a novel method suitable for numerical analysis of liquid fuel atomization. In the method, liquid is calculated by a particle method (the moving particle simulation (MPS) method using JAXA’s software “P-flow”),・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22ECMP23 Subject Category: Competitive Funding PDF Responsible Representative: Arizono Hitoshi, Aeronautical Technology Directorate, Aviation Environmental Sustainability Innovation Hub Contact Information: higo.ayumi@subaru.co.jp(higo.ayumi@subaru.co.jp) Members: Ayumi Higo, Tomofumi Iwamoto, Masafumi Sasaki, Hideaki Sugawara, Yasutada Tanabe Abstract 30% of the total drag of rotorcrafts is main rotor hub and mast drag. The hub fairing and the mast cowling were installed on the compound helicopter concept model developed by JAXA, and hub drag reduction effect・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22ECMP24 Subject Category: Competitive Funding PDF Responsible Representative: Noriko Yamasaki, Institute of Space and Astronautical Science, Dept. of Space Astronomy and Astrophysics Contact Information: Nagomi Uchida(uchida.nagomi@jaxa.jp) Members: Nagomi Uchida Abstract Recently, pulse-phase modulations of X-ray pulsation are found from some strongly magnetized neutron stars (Magnetars). This can be interpreted as the presence of free precession and thus they are deformed to prolate spheroid. We verify these results with independently developed・・・<<read more>>
