Deep learning interfacial momentum closures in coarse-mesh CFD two-phase flow simulation using validation data
INTERNATIONAL JOURNAL OF MULTIPHASE FLOW, 135.
author keywords: Machine learning; CFD; Two-phase flow; Interfacial forces; Coarse mesh
TL;DR:
FSM can substantially improve the prediction of the coarse-mesh CFD model, regardless of the choice of interfacial closures, and it provides scalability and consistency across discontinuous flow regimes, demonstrating that data-driven methods can aid the multiphase flow modeling by exploring the connections between local physical features and simulation errors.

2021 review
Uncertainty quantification and software risk analysis for digital twins in the nearly autonomous management and control systems: A review
[Review of ]. ANNALS OF NUCLEAR ENERGY, 160.
author keywords: Digital twin; Autonomous control; Uncertainty quantification; Software risk analysis
TL;DR:
This study selects and reviews relevant UQ techniques and software hazard and software risk analysis methods that may be suitable for DTs in the NAMAC system and evaluates the uncertainty of DTs and its impacts on the reactor digital instrumentation and control systems.

2019 journal article
A data-driven framework for error estimation and mesh-model optimization in system-level thermal-hydraulic simulation
NUCLEAR ENGINEERING AND DESIGN, 349, 27–45.
Contributors: *, N. Dinh n , J. Lane* & R. Youngblood*
author keywords: Coarse mesh; Error estimation; System-level modeling and simulation; Machine learning; Physical feature
TL;DR:
A data-driven framework is formulated and demonstrated to estimate simulation error and suggest optimal selection of computational mesh size and constitutive correlations for low-f fidelity, coarse-mesh thermal-hydraulic simulation, in order to achieve accuracy comparable to that of high-fidelity simulation.
