Toward Direct Numerical Simulation of Turbulent and Transitional Flow in Hexagonal Subchannels for Helium Conditions
Carolina Bourdot Dutra, Elia Merzari
Understanding the coolant thermal hydraulics in rod bundles is essential to the design of nuclear reactors. However, flows with low Reynolds numbers present serious modeling challe…
Study on Laminar-Turbulent Transition in Square Arrayed Rod Bundles
Carolina Bourdot Dutra, Elia Merzari
The study of coolant flow behavior in rod bundles is of relevance to the design of nuclear reactors. Although laminar and turbulent flows have been researched extensively, there ar…
Validation and Comparison of HI-STORM Overpack Thermal-Hydraulic Model with MOOSE and NekRS
Sinan Okyay, Elia Merzari, David A. Reger +4
Nuclear power is a significant source of electricity in the United States, but the average U.S. nuclear power plant is around 40 years old. Safe management of spent nuclear fuel (S…
A Preliminary Fluid-Structure Coupling of NekRS and MOOSE via Cardinal
A. Chaube, A. J. Novak, H. Yuan +4
Fluid-Structure Interaction (FSI) is a significant phenomenon in most nuclear reactors, causing effects such as Flow-Induced Vibration (FIV) and thermally-driven Core-Radial Expans…
High-fidelity simulation of pebble beds: Toward an improved understanding of the wall channeling effect
David Reger, Elia Merzari, Saya Lee +2
Wall channeling is a phenomena of interest for Pebble Bed Reactors (PBRs) where flow is diverted into high-porosity regions near the wall. This diversion of flow can have a signifi…
Direct Numerical Simulation of High Prandtl Number Fluid Flow in the Downcomer of an Advanced Reactor
Tri Nguyen, Elia Merzari
The design of advanced nuclear reactors (Gen IV) involves an array of challenging fluid-flow issues that affect its safety and performance. The calculated DNS database will be inst…
