A Hybrid POD-Autoencoder Framework for Reduced Order Modeling of Turbulent Flow via Strategic Field Decomposition
Xianglong Li, Zeng Liu, Zhan Wang +3
This study proposes a hybrid reduced-order modeling (ROM) framework for the simulation of turbulent flow. The central idea is to decompose flow dynamics according to their temporal…
An ALE-Consistent Graph Neural Operator-Transformer Framework for Fluid-Structure Interaction
Shihang Zhao, Martín Saravia, Haokui Jiang +2
We propose an arbitrary Lagrangian-Eulerian (ALE)-consistent machine learning framework for long-term fluid-structure interaction (FSI) prediction on deforming unstructured meshes.…
B-spline periodization of Fourier pseudo-spectral method for non-periodic problems
Dongan Li, Mou Lin, Shunxiang Cao +1
Spectral methods are renowned for their high accuracy and efficiency in solving partial differential equations. The Fourier pseudo-spectral method is limited to periodic domains an…
Onset instability of inverted flags clamped by a cylinder
Haokui Jiang, Yujia Zhao, Burigede Liu +1
We numerically investigate the hydrodynamic characteristics and analyze the instability mechanism of a two-dimensional inverted flag clamped by a cylinder. Two transition routes an…
