A Hybrid Discretize-then-Project Reduced Order Model for Turbulent Flows on Collocated Grids with Data-Driven Closure
Nadim Rooholamin, Kabir Bakhshaei, Giovanni Stabile
This study presents a hybrid reduced-order modeling (ROM) framework for turbulent incompressible flows on collocated finite volume grids. The methodology employs the "discretize-th…

A reduced-order model for advection-dominated problems based on Radon Cumulative Distribution Transform
Tobias Long, Robert Barnett, Richard Jefferson-Loveday +2
Problems with dominant advection, discontinuities, travelling features, or shape variations are widespread in computational mechanics. However, classical linear model reduction and…
