Development of a coupling between a system thermal-hydraulic code and a reduced order CFD model
S. Kelbij Star, Giuseppe Spina, Francesco Belloni +1
The nuclear community has coupled several three-dimensional Computational Fluid Dynamics (CFD) solvers with one-dimensional system thermal-hydraulic (STH) codes. This work proposes…

Reduced order models for the incompressible Navier-Stokes equations on collocated grids using a 'discretize-then-project' approach
Sabrina Kelbij Star, Benjamin Sanderse, Giovanni Stabile +2
A novel reduced order model (ROM) for incompressible flows is developed by performing a Galerkin projection based on a fully (space and time) discrete full order model (FOM) formul…

A POD-Galerkin reduced order model of a turbulent convective buoyant flow of sodium over a backward-facing step
Kelbij Star, Giovanni Stabile, Gianluigi Rozza +1
A Finite-Volume based POD-Galerkin reduced order modeling strategy for steady-state Reynolds averaged Navier--Stokes (RANS) simulation is extended for low-Prandtl number flow. The…
