To find the optimal shape of the capsule, we perfomed CFD analyses. Reference URL N/A Reasons and benefits of using JAXA Supercomputer System There have・・・<<read more>>
JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA55 Subject Category: JSS Inter-University Research PDF Responsible Representative: Takayuki Nagata, Project Assistant Professor, Nagoya University Contact Information: Takayuki Nagata(takayuki.nagata@mae.nagoya-u.ac.jp) Members: Taku Nonomura, Takayuki Nagata Abstract Compressible flow around multiple particles placed in a flowfield is investigated by the direct numerical simulation of the Navier-Stokes equations at Reynolds number of O(10^2). The objective of the present study is to obtain fundamental insight into the effects of aerodynamic interference between particles・・・<<read more>>
JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA52 Subject Category: JSS Inter-University Research PDF Responsible Representative: Shinichiro Ogawa, Osaka Metropolitan University, Department of Aerospace and Marine-system Engineering Contact Information: Shinichiro Ogawa, Assistant Professor, Osaka Metropolitan University(shinichiro.ogawa@omu.ac.jkp) Members: Shinichiro Ogawa, Loupmael Agulles, Daisuke Sasaki Abstract The utilization of computational fluid dynamics (CFD) for reducing development costs is increasing; however, conventional analysis solvers have traditionally employed structured or unstructured grids. Nevertheless, when using structured or unstructured grids, challenges such・・・<<read more>>
JAXA Supercomputer System Annual Report February 2023-January 2024 Report Number: R23EACA53 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Tohoku University Contact Information: Yasuhito Okano, Tohoku University(yasuhito.okano.p4@dc.tohoku.ac.jp) Members: Naofumi Ohnishi, Yasuhito Okano, Hiroki Sakamoto Abstract Critical issues for designing a reentry capsule are mainly the prediction of aerodynamic heating in hypersonic flows and dynamic instability in transonic flows. In hypersonic flows, the heating rate can be increased due to the transition from the laminar to turbulence at・・・<<read more>>
