Dynamic Synchronization of Driven Self-Oscillators: Modeling and Experiment
Zhenwei Xu, Ulrich Kuhl, Nicolas Noiray
Synchronization of self-sustained oscillators under fixed-frequency and amplitude forcing is well understood, but how time-varying forcing mangles phase locking has been much less…
Restricted Euler dynamics in free-surface turbulence
Yinghe Qi, Zhenwei Xu, Filippo Coletti
The small-scale velocity gradient is connected to fundamental properties of turbulence at the large scales. By neglecting the viscous and nonlocal pressure Hessian terms, we derive…
Data-free Non-intrusive Model Reduction for Nonlinear Finite Element Models via Spectral Submanifolds
Mingwu Li, Thomas Thurnher, Zhenwei Xu +1
The theory of spectral submanifolds (SSMs) has emerged as a powerful tool for constructing rigorous, low-dimensional reduced-order models (ROMs) of high-dimensional nonlinear mecha…
Data-Driven Reduction of the Finite-Element Model of a Tribomechadynamics Benchmark Problem
Ahmed Amr Morsy, Zhenwei Xu, Paolo Tiso +1
Bolted joints can exhibit nonsmooth and significantly nonlinear dynamics. Finite Element Models (FEMs) of this phenomenon require fine spatial discretizations, inclusion of nonline…
Nonlinear Model Reduction to Random Spectral Submanifolds in Random Vibrations
Zhenwei Xu, Roshan S. Kaundinya, Shobhit Jain +1
Dynamical systems in engineering and physics are often subject to irregular excitations that are best modeled as random. Monte Carlo simulations are routinely performed on such ran…
Data-driven modeling of the regular and chaotic dynamics of an inverted flag from experiments
Zhenwei Xu, Bálint Kaszás, Mattia Cenedese +3
We use video footage of a water tunnel experiment to construct a two-dimensional reduced-order model of the flapping dynamics of an inverted flag in uniform flow. The model is obta…
