Onset of vortex shedding in flow past Rankine ovals
Zhaoyue Xu, Yi Liu, Hua-dong Yao +2
The Rankine oval is a classical geometry in potential flow, formed by superimposing a uniform stream with velocity U and a source-sink pair separated by distance 2a with strength m…
CFDagent: A Language-Guided, Zero-Shot Multi-Agent System for Complex Flow Simulation
Zhaoyue Xu, Long Wang, Chunyu Wang +5
We introduce CFDagent, a zero-shot, multi-agent system that enables fully autonomous computational fluid dynamics (CFD) simulations from natural language prompts. CFDagent integrat…
asKAN: Active Subspace embedded Kolmogorov-Arnold Network
Zhiteng Zhou, Zhaoyue Xu, Yi Liu +1
The Kolmogorov-Arnold Network (KAN) has emerged as a promising neural network architecture for small-scale AI+Science applications. However, it suffers from inflexibility in modeli…
Bayesian optimization for the spanwise oscillation of a gliding flat-plate
Chunyu Wang, Zhaoyue Xu, Xinlei Zhang +1
The kinematics of a gliding flat-plate with spanwise oscillation has been optimized to enhance the power efficiency by using Bayesian optimization method, in which the portfolio al…
