JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA18 Subject Category: JSS Inter-University Research PDF Responsible Representative: Seiichiro Morizawa, Lecturer, National Institute of Technology, Okinawa College Contact Information: Seiichiro Morizawa(morizawa@okinawa-ct.ac.jp) Members: Seiichiro Morizawa, Takashi Matsuno Abstract Birds such as hawks have excellent characteristics of flight efficiency and quiteness. One of these distingusished features is thought to be the shape of wingtip with multiple wings and gaps. The purpose of this project is to clarify these mechanisims of wingtip・・・<<read more>>
