Impact of grain boundary and surface diffusion on predicted fission gas bubble behavior and release in UO fuel
Md Ali Muntaha, Sourav Chatterjee, Sophie Blondel +4
In this work, we quantify the impact of grain boundary (GB) and surface diffusion on fission gas bubble evolution and fission gas release in UO nuclear fuel using simulations w…
A GPU-accelerated package for simulation of flow in nanoporous source rocks with many-body dissipative particle dynamics
Yidong Xia, Ansel Blumers, Zhen Li +7
Mesoscopic simulations of hydrocarbon flow in source shales are challenging, in part due to the heterogeneous shale pores with sizes ranging from a few nanometers to a few micromet…
Nonlinear Diffusion Acceleration of the Least-Squares Transport Equation in Geometries with Voids
Hans Hammer, Jim Morel, Yaqi Wang
In this paper we show the extension of the Nonlinear-Diffusion Acceleration (NDA) to geometries containing small voids using a weighted least-squares (WLS) high order equation. Eve…
A Weighted Least-Squares Transport Equation Compatible with Source Iteration and Voids
Hans Hammer, Jim Morel, Yaqi Wang
Least-squares (LS) forms of the transport equation can circumvent the void problems of other second order forms, but are almost always non-conservative. Additionally, the standard…
A Data-driven Framework for Error Estimation and Mesh-Model Optimization in System-level Thermal-Hydraulic Simulation
Han Bao, Nam Dinh, Jeffrey Lane +1
Over the past decades, several computer codes were developed for simulation and analysis of thermal-hydraulics of system behaviors in nuclear reactors under operating, abnormal tra…
Simulation of unsteady blood flows in a patient-specific compliant pulmonary artery with a highly parallel monolithically coupled fluid-structure interaction algorithm
Fande Kong, Vitaly Kheyfets, Ender Finol +1
Computational fluid dynamics (CFD) is increasingly used to study blood flows in patient-specific arteries for understanding certain cardiovascular diseases. The techniques work qui…
