Numerical analysis of fluid lubrication in line contact by using the MPS method
Autor: Hideyo NEGISHI, Hironori FUJIHARA, Hidenao TAKAHASHI, Kazuya SHIBATA, Kazuaki MANIWA, Shingo OBARA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 86, Iss 890, Pp 20-00241-20-00241 (2020)
The fluid film lubrication problem is usually solved using classical Reynolds equation-based modeling to predict fluid film behavior such as pressure distribution and oil film thickness, which requires pressure boundary conditions at the locations of

Boundary integral based polygon wall representation in the MPS method
Autor: Takuya MATSUNAGA, Kazuya SHIBATA, Seiichi KOSHIZUKA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 84, Iss 864, Pp 18-00197-18-00197 (2018)
The particle methods are suited to simulate fluid flow problems with large boundary deformation. The moving particle semi-implicit (MPS) method is one of the representative particle methods for incompressible flow. In recent years, the MPS method has

Statistical analysis of three-dimensional run-up heights using Gaussian process emulator of particle method
Autor: Yoshiki Mizuno, Seiichi Koshizuka, Kazuya Shibata
Publikováno v: Computational Particle Mechanics. 9:525-535
This study presents that an emulator of a particle method has the potential to be applied for the statistical analysis of tsunami run-up phenomena. The emulator follows a Gaussian process to model a particle method specifically for estimating wave he

Numerical modeling of floating bodies transport for flooding analysis in nuclear reactor building
Autor: Seiichi Koshizuka, Fangyuan Hu, Kazuya Shibata, Zidi Wang, Guangtao Duan
Publikováno v: Nuclear Engineering and Design. 341:390-405
The nuclear reactor safety analysis especially related to flooding accidents becomes more and more important after the Fukushima nuclear accident. In case of an internal or external flooding accident, some large floating bodies, such as broken doors,

Vacuum energy of the supersymmetric $\mathbb{C}P^{N-1}$ model on $\mathbb{R}\times S^1$ in the $1/N$ expansion
Autor: Morikawa Okuto, Hiroshi Suzuki, Kosuke Ishikawa, Kazuya Shibata
Publikováno v: Progress of Theoretical and Experimental Physics. 2020
By employing the $1/N$ expansion, we compute the vacuum energy~$E(\delta\epsilon)$ of the two-dimensional supersymmetric (SUSY) $\mathbb{C}P^{N-1}$ model on~$\mathbb{R}\times S^1$ with $\mathbb{Z}_N$ twisted boundary conditions to the second order in

Verification and validation of explicit moving particle simulation method for application to internal flooding analysis in nuclear reactor building
Autor: Kazuya Shibata, Seiichi Koshizuka, Zidi Wang
Publikováno v: Journal of Nuclear Science and Technology. 55:461-477
The Fukushima nuclear accident raised the importance of flooding study in nuclear reactor buildings. It is known that the external flooding can be attributed to natural causes, while the internal f...
