Shape optimization for trailing-edge noise reduction using large-eddy simulation and ensemble-based method
Qingyong Luo, Xin-Lei Zhang, Guowei He
In this work, the trailing-edge shape of an airfoil is optimized to reduce the acoustic noise based on large-eddy simulation (LES). It is achieved by the ensemble Kalman method, wh…
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…
A framework for learning symbolic turbulence models from indirect observation data via neural networks and feature importance analysis
Chutian Wu, Xin-Lei Zhang, Duo Xu +1
Learning symbolic turbulence models from indirect observation data is of significant interest as it not only improves the accuracy of posterior prediction but also provides explici…
Optimizing flow control with ensemble Kalman method for mitigating flow-induced vibration
Liu Yi, Wang Shizhao, Zhang Xin-Lei +1
The ensemble Kalman method is introduced for optimizing flow control strategies in order to mitigate the flow-induced vibration of structures. Different types of control strategies…
