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…

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^…
