JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA28 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Seiji Zenitani, Researcher, Kyoto University Contact Information: Seiji Zenitani(zenitani@rish.kyoto-u.ac.jp) Members: Seiji Zenitani, Iku Shinohara, Takahiro Miyoshi 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 develop massively-parallel simulation codes. They・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA26 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Kengo Asada, Tokyo University of Science, Department of Information and Computer Technology, Postdoctoral Researcher Contact Information: Kengo Asada(asada@rs.tus.ac.jp) Members: Kengo Asada, Takuto Ogawa Abstract The project develops flow control technic by using dielectric barrier discharge (DBD) plasma actuator to establish high efficient and robust vehicle systems such as rockets, aircrafts, and motor vehicles. We propose and demonstrate feedback control methods to・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA21 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Ayano Inatomi(inatomi-ayano-ng@ynu.jp) Members: Ayano Inatomi, Keiichi Kitamura Abstract Generally, aircraft and rockets are slender bodies whose cross sections are close to a circle. In these slender bodies, the aerodynamic characteristics greatly change at a large angle of attack (AoA). As an influence from the change in the aerodynamic characteristics, for example, the・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA20 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Toshiaki Harada(harada-toshiaki-vt@ynu.jp) Members: Toshiaki Harada, Keiichi Kitamura 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・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA13 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Kazuo Matsuura, Associate Professor, Ehime University, Graduate School of Science and Engineering Contact Information: Kazuo Matsuura(matsuura.kazuo.mm@ehime-u.ac.jp) Members: Kazuo Matsuura Abstract In hypersonic transitional flows, there are many complicated factors such as density fluctuation and temperature fluctuation due to the co-existence of the region slower than the speed of sound and the region faster than the speed of sound inside the boundary・・・<<read more>>
