JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18ETET12 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Takahashi(Aeronautical Technology Directorate) Contact Information: Aeronautical Technology Directorate, Numerical Simulation Research Unit(ohmichi.yuya@jaxa.jp) Members: Kenji Kobayashi Abstract Typical blunt bodies often show dynamic instability in subsonic and transonic regimes because of unsteady aerodynamic forces driven by complicate wake structures. In this study, we numerically simulated the flowfield around the capsule under the forced pitch oscillation motion, to investigate the flow structure・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18ETET05 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Aoyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Himeko Yamamoto(himeko@toki.waseda.jp) Members: Himeko Yamamoto Abstract For the development of a aircraft engine combustor with high environmental compatibility, we develop the combustion calculation method that can reproduce the pressure propagation and chemical reaction with practical calculation cost. In addition, a verification calculation of this calculation method is conducted on the・・・<<read more>>
