In this study, we have been developing knowledge extraction・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21ECWU12 Subject Category: Cooperative Graduate School System PDF Responsible Representative: Yuya ohmichi, Aeronautical Technology Directorate,Numerical Simulation Research Unit Contact Information: Yuya ohmichi (ohmichi.yuya@jaxa.jp) Members: Miumi Maezawa, Yuya Ohmichi Abstract It is well known that rectangular-shaped cavities, such as those found in aircraft landing gear storage areas, can cause noise due to self-excited oscillation caused by an unsteady fluid phenomenon. In this study, the phenomenon of self-excited oscillation inside cavities was・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA16 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Tohoku University Contact Information: Naofumi Ohnishi(naohnishi@tohoku.ac.jp) Members: Naofumi Ohnishi, Shintaro Sato, Hideto Tamura Abstract Plasma actuator has attracted attention as a fluid control device using dielectric barrier discharge. In the experimental study, it has been pointed out that the discharge has a spanwise distribution of the electrode and has a three-dimensional structure. In this study, we perform the・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA50 Subject Category: JSS Inter-University Research PDF Responsible Representative: Yutaro Motoori, Assistant Professor, Osaka University Contact Information: Yutaro Motoori (y.motoori.es@osaka-u.ac.jp) Members: Yutaro Motoori Abstract Turbulence is ubiquitous in many phenomena around us. Since turbulent flow mixes and diffuses mass rapidly, it is important to understand the transport phenomena by turbulence in many systems. In the present study, we reveal the transport mechanism of particles in fully developed inhomogeneous turbulence. For・・・<<read more>>
