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>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA35 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Edyta Dzieminska, Sophia University Contact Information: Tang Xinmeng, Sophia University(simondonxq@gmail.com) Members: Edyta Dzieminska, Koichi Hayashi, Xinmeng Tang, Wataru Koido Abstract This research is to develop a 3D program with generalized coordinate system, that provides a flexible, efficient, accurate and have a compatible detailed chemical reaction system, for combustion and detonation issues. This program simulates combustion flows (especially combustion of hydroxygen mixture)・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA31 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Soshi Kawai, Professor, Tohoku University Contact Information: Ryo Hirai(hirai@klab.mech.tohoku.ac.jp) Members: Soshi Kawai, Ryo Hirai, Yuki Mori Abstract LES study of near-wall turbulent physics in heated/cooled-wall compressible turbulent boundary layers is conducted. The study reveals the relation between the mean-velocity profiles and turbulent structures in the conditions with wall heat flux. Also, Further, based on knowledge obtained in the LES study, improved・・・<<read more>>
