JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19ECMP10 Subject Category: Competitive Funding PDF Responsible Representative: Yasutada Tanabe, Aeronautical Technology Directorate, Aviation Systems Research Unit Contact Information: Yasutada Tanabe(tan@chofu.jaxa.jp) Members: Yasutada Tanabe, Hideaki Sugawara, Kuniyuki Takekawa, Masafumi Sasaki Abstract Compound helicopter is one of the next-generation rotorcraft to achieve high-speed flight. However, the increased drag due to the aerodynamic interaction between the rotor and the fixed-wing is one of the technology issues for this type of rotorcraft. The・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19ECMP08 Subject Category: Competitive Funding PDF Responsible Representative: Shingo Matsuyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Shingo Matsuyama(smatsu@chofu.jaxa.jp) Members: Shingo Matsuyama Abstract In this study, we aim to realize a comprehensive LES that does not require any tuning for model parameters to the target flow field by solving the SGS stress transport equations. The SGS stress equations are derived exactly from the spatial filtering operation, but requires・・・<<read more>>
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>>
