JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA43 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate professor, Yokohama National University Contact Information: Suguru Ogawa(ogawa-suguru-ps@ynu.jp) Members: Keiichi Kitamura, Suguru Ogawa, Yoshikatsu Furusawa Abstract As a new form of vheicle of the Mars explolation, research and development of Mars airplanes are progressing mainly in JAXA in Japan. Since the Martian atmosphere has a low density and Mars airplanes fly in the low Reynolds number region, it・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA38 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Hiroyuki Asada, Department of Mechanical Engineering, Ritsumeikan University. Contact Information: Hiroyuki Asada(asahiro.cfd.1601@gmail.com) Members: Hiroyuki Asada, Yoshifumi Ogami, Daisuke Nishida, Shinya Endo, Kazuki Miyata Abstract This study aims to develop a high-fidelity solver for aeroacoustics simulations. The solver is based on the high-order discontinuous Galerkin (DG) method which is one of the high-order unstructured mesh methods and the large eddy simulation giving・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA37 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Soshi Kawai, Professor, Department of Aerospace Engineering, Tohoku University Contact Information: Ryo Kamogawa(kamogawa@klab.mech.tohoku.ac.jp) Members: Soshi Kawai, Sayako Ishitsuka, Ryo Kamogawa Abstract In this study, wall-resolved large-eddy simulation (WRLES) and wall-modeled LES (WMLES) were conducted to clarify the mechanisms of turbulence generation in WMLES, and also to investigate the predictability of WMLES of the separated flow. From the results, we found that・・・<<read more>>
