An Efficient and Accurate Surrogate Modeling of Flapping Dynamics in Inverted Elastic Foils using Hypergraph Neural Networks
Aarshana R. Parekh, Rui Gao, Rajeev K. Jaiman
Cantilevered elastic foils can undergo self-induced, large-amplitude flapping when subject to fluid flow, a widely observed phenomenon of fluid-structure interaction, from flutteri…
Propulsive transitions and scaling relations of a heaving flexible foil in a cylinder wake
Guojun Li, Lanlan Wang, Weitao Jiang +2
We numerically investigate the propulsive dynamics of a heaving flexible foil immersed in the wake of a stationary circular cylinder, focusing on the coupled effects of unsteady wa…
Predicting Flow-Induced Vibration in Isolated and Tandem Cylinders Using Hypergraph Neural Networks
Shayan Heydari, Rui Gao, Rajeev K Jaiman
We present a finite element-inspired hypergraph neural network framework for predicting flow-induced vibrations in freely oscillating cylinders. The surrogate architecture transfor…
A Mesh-Adaptive Hypergraph Neural Network for Unsteady Flow Around Oscillating and Rotating Structures
Rui Gao, Zhi Cheng, Rajeev K. Jaiman
Graph neural networks, recently introduced into the field of fluid flow surrogate modeling, have been successfully applied to model the temporal evolution of various fluid flow sys…
A Graph Neural Network Surrogate Model for Multi-Objective Fluid-Acoustic Shape Optimization
Farnoosh Hadizadeh, Wrik Mallik, Rajeev K. Jaiman
This article presents a graph neural network (GNN) based surrogate modeling approach for fluid-acoustic shape optimization. The GNN model transforms mesh-based simulations into a c…
Self-sustained oscillations in whiskers without vortex shedding
Shayan Heydari, Mitra J. Z. Hartmann, Neelesh A. Patankar +1
Sensing the flow of water or air disturbance is critical for the survival of many animals: flow information helps them localize food, mates, and prey and to escape predators. Acros…
