JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA37 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Soshi Kawai, Associate Professor, Tohoku University Contact Information: Sayako Ishitsuka(ishitsuka@cfd.mech.tohoku.ac.jp) Members: Sayako Ishitsuka, Ryo Hirai, Soshi Kawai Abstract The first purpose in this study is to investigate the detailed mechanisms of the flow separation control with vortex-generator (VG) by using large eddy simulation (LES) of compressible turbulent boundary layer flows. The second purpose is to verify the predictability of near-wall turbulence・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA31 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Soshi Kawai, Associate Professor, Tohoku University Contact Information: Ryo Hirai(hirai@cfd.mech.tohoku.ac.jp) Members: Soshi Kawai, Kosuke Totani Abstract In this study, we first analyze compressible thermal turbulent boundary layers on a flat plate including the heat flux such as cooling/heating from the wall surface using LES, and then we aim to construct reliable wall modeling in LES which can evaluate the effects of・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA14 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Ko-ichiro Sugiyama, Associate Professor, National Institute of Technology, Matsue College Contact Information: Ko-ichiro Sugiyama(sugiyama@gfd-dennou.org) Members: Hiroki Ando, Ko-ichiro Sugiyama Abstract Our purpose is to support the observation performed by AKATSUKI (Venus Climate Orbiter) by developing a numerical fluid dynamics model (cloud resolving model) and providing a lot of numerical simulation data. The motion of Venus' cloud-level convection and the propagation of・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA12 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Yuya Takagi(takagi-yuuya-ks@ynu.jp) Members: Keiichi Kitamura, Yuya Takagi Abstract In this study, we attempted to improve the aerodynamic characteristics by attaching delta-wings and vortex-flaps to a slender body. Since the thickness of the fins is small, it is difficult to carry out the wind tunnel experiment. However, we succeeded in acquiring aerodynamic characterisitics・・・<<read more>>
