JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20ECMP10 Subject Category: Competitive Funding PDF Responsible Representative: Yoshikazu Makino, Aeronautical Technology Directorate, Aviation Systems Research Unit Contact Information: Yasutada Tanabe(tan@chofu.jaxa.jp) Members: Yasutada Tanabe, Hideaki Sugawara, Masahiko Sugiura, Kuniyuki Takekawa, Masafumi Sasaki, Keita Kimura Abstract A compound helicopter is one of the high-speed rotorcraft concepts. Aerodynamic interactions occur on the winged compound helicopter, constructed by a single main rotor, winged-body, and multiple propellers. The drag of the rotorcraft drastically increases・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20ECMP08 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>>
