Large-eddy simulations of turbulent flow for grid-to-rod fretting in nuclear reactors
TL;DR: In this article, an implicit large-eddy simulation of rod-bundle flows is used to calculate the excitation forces for the grid-to-rod fretting (GTRF) problem.
Journal ArticleDOI
Large-eddy simulation, fuel rod vibration and grid-to-rod fretting in pressurized water reactors
Mark A. Christon,Roger Y. Lu,Jozsef Bakosi,Balasubramanya T. Nadiga,Zeses E. Karoutas,Markus Berndt +5 more
TL;DR: A new approach for predicting GTRF induced fuel rod wear that uses high-resolution implicit large-eddy simulation to drive nonlinear transient dynamics computations and can be used to improve reactor core designs in which fuel rod failures are minimized or potentially eliminated.
Journal ArticleDOI
Fluid flow investigations within a 37 element CANDU fuel bundle supported by magnetic resonance velocimetry and computational fluid dynamics
Markus H.A. Piro,F. Wassermann,Sven Grundmann,Sven Grundmann,B. Tensuda,Seung Jun Kim,Mark A. Christon,Markus Berndt,M. Nishimura,M. Nishimura,Cameron Tropea +10 more
TL;DR: In this paper, the authors present experimental and computational investigations of fluid flow through a 37 element CANDU nuclear fuel bundle using Magnetic Resonance Velocimetry (MRV) experiments.
Journal ArticleDOI
Multi-material incompressible flow simulation using the moment-of-fluid method†
Samuel P. Schofield,Mark A. Christon,Vadim Dyadechko,Rao V. Garimella,Robert B. Lowrie,Blair Swartz +5 more
TL;DR: The Moment-of-Fluid interface reconstruction technique is implemented in a second order accurate, unstructured finite element variable density incompressible Navier-Stokes solver as mentioned in this paper.
Proceedings ArticleDOI
HPCCloud: A Cloud/Web-Based Simulation Environment
TL;DR: This paper describes the development of an end-to-end, advanced modeling and simulation cloud platform that encapsulates best practices for scientific computing in the cloud, and demonstrates using Hydra-TH as a prototypical application.
