Reduced-order modelling based on Koopman operator theory (2409.03549v1)
Published 5 Sep 2024 in math.NA, cs.NA, and math.DS
Abstract: The present study focuses on a subject of significant interest in fluid dynamics: the identification of a model with decreased computational complexity from numerical code output using Koopman operator theory. A reduced-order modelling method that incorporates a novel strategy for identifying the most impactful Koopman modes was used to numerically approximate the Koopman composition operator.
