Variational Multiscale Evolve and Filter Strategies for Convection-Dominated Flows
Maria Strazzullo, Francesco Ballarin, Traian Iliescu +1
The evolve-filter (EF) model is a filter-based numerical stabilization for under-resolved convection-dominated flows. EF is a simple, modular, and effective strategy for both full-…
A Priori Error Bounds for the Approximate Deconvolution Leray Reduced Order Model
Ian Moore, Anna Sanfilippo, Francesco Ballarin +1
The approximate deconvolution Leray reduced order model (ADL-ROM) uses spatial filtering to increase the ROM stability, and approximate deconvolution to increase the ROM accuracy.…
A Priori Error Bounds for POD-ROMs for Fluids: A Brief Survey
Francesco Ballarin, Traian Iliescu
Galerkin reduced order models (ROMs), e.g., based on proper orthogonal decomposition (POD) or reduced basis methods, have achieved significant success in the numerical simulation o…
