Evaluation of Statistical Consistency in Synthetic Turbulence under Wavenumber Bounds
Hongyuan Lin, Yi Liu, Shizhao Wang +1
The random Fourier method (RFM) is widely employed for synthetic turbulence due to its mathematical clarity and simplicity. However, deviations remain between prescribed inputs and…
Distributed force element decomposition with method of fundamental solutions
Zhiteng Zhou, Yi Liu, Hongping Wang +1
Quantifying the contribution of vortex structures to pressure stress is useful for designing flow control strategies to mitigate low or drag. The traditional force-element method f…
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…
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…
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…
