What information do the DMD modes provide about the spatial structure of the dynamics?

KEY WORDS: heat · fluid, computational fluid dynamics, aerodynamic performance, Dynamic Mode Decomposition [D1] ... dominant modes from dynamic mode decomposition ... Used to analyze the time-evolution of fluid flows, dynamic mode decomposition. (DMD) has quickly gained traction in the fluids community. In this paper, we propose Bayesian DMD, which provides a principled way to transfer the advantages of the Bayesian formulation into DMD. To this end, we first ... Mar 19, 2019 ... Dynamic mode decomposition has emerged as a leading technique to identify spatiotemporal coherent structures from high-dimensional data, ... Jul 14, 2020 ... Dynamic mode decomposition (DMD) is a purely data-driven and equation-free technique for reduced-order modeling of dynamical systems and fluid flow. Title, 24. DGLR STAB-Symposium. Duration, 13 - 14 November 2024. Degree of recognition, National event. Location, OTH Regensburg. City, Regensburg. Feb 13, 2025 ... Based on simple least-square regression, the underlying dynamic mode decomposition algorithm can be used to construct a low-rank subspace ... ...
