Report Number: R16E0056 Responsible Representative: Yoshiaki Abe(Department of Mechanical Engineering, Tokyo Institute of Technology) Contact Information: Yoshiaki Abe(y.abe@imperial.ac.uk) Members: Yoshiaki Abe Subject Category: Basic Research(Numerical analysis,CFD) Abstract We have investigated a coupling of very-high-order flux-reconstruction scheme and kinetic energy preserving framework for simulating high-Reynolds-number flows around complex geometries using parallel computers. Several numerical experiments have been conducted for isotropic turbulence without excessive numerical dissipation. Goal This project focuses on a development of numerical methodologies for high-fidelity flow simulations on a・・・<<read more>>
Report Number: R16E0055 Responsible Representative: Keiichi Kitamura(Yokohama National University) Contact Information: Ayano Inatomi(inatomi-ayano-ng@ynu.jp) Members: Ayano Inatomi, Takuya Aogaki, Keiichi Kitamura Subject Category: Space(Space transportation) Abstract In this study, we investigated details of flow field around the slender-bodied-vehicle numerically with configurations having different fineness ratios. Interestingly, the trend of 140 degrees of AOA is totally opposite to that observed at 50 degrees of AOA. It had been considered that the large nose bluntness and the small fineness ratio can reduce asymmetry・・・<<read more>>
Report Number: R16E0054 Responsible Representative: Toshiaki Harada(Yokohama National University) Contact Information: Toshiaki Harada(harada-toshiaki-vt@ynu.jp) Members: Toshiaki Harada, Takuya Aogaki, Keiichi Kitamura Subject Category: Space(Rocket) Abstract It is important for rocket developments to quantitatively estimate the influence of protuberances in the flight vehicles which create asymmetry of flow around the vehicles and aerodynamic forces. Using fluid numerical computation, it is expected that we obtain a guideline for the protuberance choice in the future rocket development by conducting systematic and fundamental aerodynamic study・・・<<read more>>
Report Number: R16E0053 Responsible Representative: Junko Kominami(Tokyo Institute of Technology) Contact Information: Masaki Fujimoto(fujimoto.masaki@jaxa.jp) Members: Junko Kominami Subject Category: Space(Space science) Abstract Planets are thought to be formed from dust in protoplanetary disks. However, so far, we have not succeeded to reproduce even our Solar system. I am carrying out N-body simulation in order to clarify how the planetary system was formed. Goal Protoplanet forms in a gas disk. We include the gas drag and type-I migration due to the・・・<<read more>>
Report Number: R16E0052 Responsible Representative: Seiichiro Morizawa(Tottori University) Contact Information: Seiichiro Morizawa(morizawa@mech.tottori-u.ac.jp) Members: Seiichiro Morizawa Subject Category: Space(Space engineering) Abstract It is necessary to understand the flow field under low Reynold and high Mach numbers conditions when we conduct the aerodynamic design for Mars exploration airplane. However, there is few studies on the flow field. Thus, we conduct the fluid simulations under the condition and aim to obtain the information of aerodynamic design for the airplane. Goal The Martian atmosphere・・・<<read more>>
