JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA37 Subject Category: JSS Inter-University Research PDF Responsible Representative: Soshi Kawai, Professor, Department of Aerospace Engineering, Tohoku University Contact Information: Hiroyuki Asada(h.asada@tohoku.ac.jp) Members: Soshi Kawai, Ryo Kamogawa, Hiroyuki Asada, Aya Aihara Abstract To accurately simulate turbulent flows with separation and reattachment using wall-modeled large-eddy simulation (LES), non-equilibrium effects, such as the effects of the pressure gradient, should be incorporated in the wall model. However, the existing non-equilibrium wall-models require solving・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA31 Subject Category: JSS Inter-University Research PDF Responsible Representative: Soshi Kawai, Professor, Tohoku University Contact Information: Ryo Hirai(ryo.hirai.q7@dc.tohoku.ac.jp) Members: Soshi Kawai, Yoshiharu Tamaki, Ryo Hirai Abstract In this study, near-wall turbulent statistics and structures of compressible turbulent boundary layers on heated and cooled wall are investigated. To evaluate the contributions of local Reynolds number changes within boundary layers caused by wall temperatures to wall turbulence, numerical simulations of a fluid・・・<<read more>>
