JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA52 Subject Category: JSS Inter-University Research PDF Responsible Representative: Shinichiro Ogawa, Assistant professor, Osaka Metropolitan University Contact Information: Shinichiro Ogawa, Assistant professor, Osaka Metropolitan University(shinichiro.ogawa@omu.ac.jp) Members: Shinichiro Ogawa, Daisuke Sasaki Abstract The Building-Cube Method (BCM), which is based on a Cartesian mesh and can easily handle the analysis of complex geometries, is useful to improve the computational performance. In this study, we develop a BCM solver for internal flow fields・・・<<read more>>
JAXA Supercomputer System Annual Report February 2022-January 2023 Report Number: R22EACA53 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Tohoku University Contact Information: Hiroki Sakamoto, Tohoku University(hiroki.sakamoto.s1@dc.tohoku.ac.jp) Members: Naofumi Ohnishi, Yasuhito Okano, Hiroki Sakamoto Abstract An expansion tube, a ground-based facility that generates hypersonic flow, is expected to be a shock wind tunnel that can experimentally simulate the flow at superorbital reentry. There is concern that turbulent transition in the expansion tube may have adverse effects on・・・<<read more>>
