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…
Towards high-fidelity wind farm layout optimization using polynomial chaos expansion and Kriging model
Yi-Xiao Shao, Zhen-Fan Wang, Shine Win Naung +3
This paper presents a wind farm layout optimization framework that integrates polynomial chaos expansion, a Kriging model, and the expected improvement algorithm. The proposed fram…
An adaptive switch strategy for acquisition functions in Bayesian optimization of wind farm layout
Zhen-fan Wang, Yu Tu, Kai Zhang +2
Wind farm layout optimization (WFLO), which seeks to maximizing annual energy production by strategically adjusting wind turbines' location, is essential for the development of lar…
Effects of Thom disk on alleviating ground effects of a wall-mounted rotating cylinder
Bao-Yuan Zhao, Kai Zhang, Dai Zhou +2
This study investigates the effects of Thom disks on alleviating ground effects by wall-mounted rotating cylinders, also known as Flettner rotors, which utilize wind energy for shi…
