Generalizable super-resolution turbulence reconstruction from minimal training data
Wu Haokai, Cao Yong, Chen Yaoran +4
Fully resolving turbulent flows remains challenging due to turbulent systems' multiscale complexity. Existing data-driven approaches typically demand expensive retraining for each…
Symmetry-breaking bifurcations and sub-harmonic lock-in of a flexible splitter plate in cylinder wake flow
Baiyang Song, Huan Ping, Wenli Chen +2
This paper investigates the flow past a flexible splitter plate attached to the rear of a fixed circular cylinder at a low Reynolds number of 150. A systematic exploration of the p…
Wake dynamics of finite-aspect-ratio rotating circular cylinders at low Reynolds number
Kai Zhang, Yong Cao, Hanfeng Wang +3
We perform direct numerical simulations of flows over finite-aspect-ratio rotating circular cylinders at a Reynolds number of 150 over a range of aspect ratios () and rota…
High-flexibility reconstruction of small-scale motions in wall turbulence using a generalized zero-shot learning
Haokai Wu, Kai Zhang, Dai Zhou +3
This study proposes a novel super-resolution (or SR) framework for generating high-resolution turbulent boundary layer (TBL) flow from low-resolution inputs. The framework combines…
An optimization framework for wind farm layout design using CFD-based Kriging model
Zhenfan Wang, Yu Tu, Kai Zhang +3
Wind farm layout optimization (WFLO) seeks to alleviate the wake loss and maximize wind farm power output efficiency, and is a crucial process in the design of wind energy projects…
Reynolds number effects on the bistable flows over a wavy circular cylinder
Kai Zhang, Hongbo Zhu, Yong Cao +1
The wake of wavy cylinder has been shown to exhibit bistability. Depending on the initial condition, the final state of the wake can either develop into a steady flow (state I), or…
