JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA45 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Toshiharu Mizukaki, Professor, Tokai University Contact Information: Toshiharu Mizukaki(mzkk@tsc.u-tokai.ac.jp) Members: Toshiharu Mizukaki, Hatsuming Wang Abstract Detonation waves is a self-sustaining combustion wave. By using the detonation waves, a propulsion system which has a high-thermal efficiency and a thrust efficiency, compared with the ordinaly engines, would be made. The porpose of this research is to establish a process of numerical analysis on・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA44 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Taku nonomura, Associate Professor, Tohoku University Contact Information: Taku Nonomura (Tohoku University)(nonomura@aero.mech.tohoku.ac.jp) Members: Taku Nonomura, Takayuki Nagata Abstract In the present study, we investigated the fundamental characteristics of the supersonic vortex generator implemented on the slip wall by the direct numerical simulation of the Navier-Stokes equation. The characteristics of the flow over vortex generators at subsonic and transonic conditions have been・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19EACA42 Subject Category: JSS2 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>>
