Stable self-adaptive timestepping for Reduced Order Models for incompressible flows

Josep Plana-Riu, Henrik Rosenberger, Benjamin Sanderse +1

This work introduces RedEigCD, the first self-adaptive timestepping technique specifically tailored for reduced-order models (ROMs) of the incompressible Navier-Stokes equations. B…

Exact operator inference with minimal data

Henrik Rosenberger, Benjamin Sanderse, Giovanni Stabile

This work introduces a novel method to generate snapshot data for operator inference that guarantees the exact reconstruction of intrusive projection-based reduced-order models (RO…

A pressure-free long-time stable reduced-order model for two-dimensional Rayleigh-Bénard convection

Krishan Chand, Henrik Rosenberger, Benjamin Sanderse

The present work presents a stable POD-Galerkin based reduced-order model (ROM) for two-dimensional Rayleigh-Bénard convection in a square geometry for three Rayleigh numbers: $10^…

No pressure? Energy-consistent ROMs for the incompressible Navier-Stokes equations with time-dependent boundary conditions

Henrik Rosenberger, Benjamin Sanderse

This work presents a novel reduced-order model (ROM) for the incompressible Navier-Stokes equations with time-dependent boundary conditions. This ROM is velocity-only, i.e. the sim…

Momentum-conserving ROMs for the incompressible Navier-Stokes equations

Henrik K. E. Rosenberger, Benjamin Sanderse

Projection-based model order reduction of an ordinary differential equation (ODE) results in a projected ODE. Based on this ODE, an existing reduced-order model (ROM) for finite vo…

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…
