JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA43 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate professor, Yokohama National University Contact Information: Yoshikatsu Furusawa(furusawa-yoshikatsu-vz@ynu.jp) Members: Keiichi Kitamura, Yoshikatsu Furusawa Abstract As a new form of a Mars exploration vehicle, research and development of a Mars airplane are progressing. Since the Martian atmosphere is low density and the Mars airplane flies in the low Reynolds number region, the flow field around the Mars airplane differs・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA42 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keichi Takahashi, Assistant Professor, Nara Institute of Science and Technology Contact Information: Keichi Takahashi(keichi@is.naist.jp) Members: Keichi Takahashi Abstract Conventional post-processing of CFD simulations was achieved by saving the entire simulation output on a parallel file system and then processing the output. However, this approach is becoming increasingly challenging due to the limitations in storage size and IO bandwidth. Therefore, data staging,・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA41 Subject Category: JSS Inter-University Research PDF Responsible Representative: Makoto Sato, Associate Professor, Kogakuin University Contact Information: Makoto Sato, Kogakuin University(msato@cc.kogakuin.ac.jp) Members: Makoto Sato, Daichi Ogasawara Abstract Mars helicopter project is now going. Since the atomospheric density on Mars is about 1/100, the sound of speed is about 3/4 compared with those on Earth, we need to develop the high perfmance heli-rotar. In JAXA, the experimental measurements of the heli-rotar・・・<<read more>>
