JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA12 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Tomohiro Mamashita(mamashita-tomohiro-nj@ynu.jp) Members: Keiichi Kitamura, Tomohiro Mamashita Abstract In this study, we work on predicting aerodynamic characteristics of the "RV-X", which is an experimental vehicle planned for flight tests. We conducted wind tunnel tests and numerical analysis supposing the low-speed flow during the return flight. The results of the numerical calculations were・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA55 Subject Category: JSS Inter-University Research PDF Responsible Representative: Takayuki Nagata, Project Assistant Professor, Tohoku University Contact Information: Takayuki Nagata(nagata@tohoku.ac.jp) Members: Taku Nonomura, Takayuki Nagata Abstract Compressible flow around twin particles is investigated by the direct numerical simulation of the Navier-Stokes equations at Reynolds number of O(10^2). The objective of the present study is to obtain fundamental insight into the effects of aerodynamic interference between particles in subsonic to supersonic・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA49 Subject Category: JSS Inter-University Research PDF Responsible Representative: Taku Nonomura, Associate Professor, Tohoku University Contact Information: Taku Nonomura(nonomura@tohoku.ac.jp) Members: Taku Nonomura, Takayuki Nagata Abstract Large-eddy simulations (LES) of the compressible flow around the plate with Reynolds numbers of O (10^3) -O (10^4) are performed. The compressibility effects on the laminar separation bubble formed around the leading edge of the flat plate and turbulent transition are investigated. The flat plate・・・<<read more>>
