JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA34 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Ryo Nagata, Researcher, High Energy Accelerator Research Organization (KEK) Contact Information: Ryo Nagata(rnagata@post.kek.jp) Members: Ryo Nagata Abstract Primordial gravitational wave background is generically predicted by cosmic inflation theories. Its amplitude indicates the energy scale of cosmic inflation. LiteBIRD maps the polarization of microwave background sky to detect the signal of the gravitational waves. Since the signal of gravitational wave origin (B-mode・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18EACA05 Subject Category: JSS2 Inter-University Research PDF Responsible Representative: Susumu Goto, Professor, Osaka University Contact Information: Susumu Goto(goto@me.es.osaka-u.ac.jp) Members: Susumu Goto, Jun Kanki, Yutaro Motoori, Toru Kubo, Tomoyuki Kurita, Ryo Araki, Tsukasa Shinohara Abstract Flows in various systems appearing in the aerospace engineering are fully developed turbulence at high Reynolds numbers. To numerically simulate these flows, we usually need to model small-scale motions in the flow. Such turbulence models are・・・<<read more>>
