JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EA0714 Subject Category: Aeronautical Technology PDF Responsible Representative: Toshiya Nakamura, Aeronautical Technology Directorate, Next Generation Aeronautical Innovation Hub Center Contact Information: Mitsumasa Makida makida.mitsumasa@jaxa.jp Members: Mitsumasa Makida(JAXA), Naoki Nakamura(ASIRI) Abstract In the development process of aircraft combustors, air mass flow distribution between fuel nozzles, dilution and cooling air holes on the liner effects performances of combustors. So it is important to understand the internal flow and estimate the mass flow・・・<<read more>>
JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EA2111 Subject Category: Aeronautical Technology PDF Responsible Representative: Takashi Yamane, Propulsion Research Unit, Aeronautical Technology Directorate Contact Information: Junichi Kazawa kazawa.junichi@jaxa.jp Members: Junichi Kazawa, Takahiro Kawahara Abstract In the turbomachine internal flow, the separation on the blade surface and the behavior of the vortex have a large influence on the aerodynamic performance. In numerical analysis using RANS, it is difficult to simulate the separation and vortex in detail, so we・・・<<read more>>
JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EACA21 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Keiichi Kitamura,Yokohama National University Contact Information: Ayano Inatomi inatomi-ayano-ng@ynu.jp Members: Ayano Inatomi, Takuya Aogaki, Keiichi Kitamura 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 Re=6x10^6 is totally opposite to that observed in Re=6x10^5 at 140 degrees of AOA. It was found that the configuration where・・・<<read more>>
JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EA2120 Subject Category: Aeronautical Technology PDF Responsible Representative: Takashi Yamane, Aeronautical Technology Directorate, Propulsion Research Unit Contact Information: Mitsumasa Makida makida.mitsumasa@jaxa.jp Members: Mitsumasa Makida, Shunji Enomoto, Junichi Kazawa, Atsushi Hashimoto, Takashi Ishida, Shigeru Kuchiishi, Taisuke Nambu(JAXA), Hiroki Ugajin, Tanaka Uhi, Yani Naoki(IHI) Abstract Unstructured-grid flow solver FaSTAR and grid generator BOXFUN are applied to aero-engine elements with complicated configuration (such as linear and rotating cascades). Through the calculation, these programs・・・<<read more>>
JAXA Supercomputer System Annual Report April 2017-March 2018 Report Number: R17EACA28 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Seiji Zenitani, Research Institute for Sustainable Humanosphere, Kyoto University Contact Information: Seiji Zenitani zenitani@rish.kyoto-u.ac.jp Members: Seiji Zenitani, Takahiro Miyoshi, Iku Shinohara Abstract This project investigates basic processes in space plasmas, by using supercomputer simulations. In particular, we study "magnetic reconnection" in space, an abrupt change in magnetic topology. In order to support research activities by ourselves and by other groups, we・・・<<read more>>
