JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA58 Subject Category: JSS Inter-University Research PDF Responsible Representative: Shintaro Sato, Assistant professor, Tohoku University Contact Information: Shintaro Sato(satoshin@rhd.mech.tohoku.ac.jp) Members: Shintaro Sato, Hibiki Tomie Abstract Flow separation control in fluid machinery is an important factor in terms of energy loss. Vortex generators, for example, can suppress separation, but they work only under specific conditions. Active flow control is required to function under a variety of conditions. In recent years, the・・・<<read more>>
