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…

Bistability in the wake of a wavy cylinder
Kai Zhang, Dai Zhou, Hiroshi Katsuchi +3
We investigate the wake dynamics of an optimally designed wavy cylinder that completely suppresses the Kármán vortex shedding. Such a wavy cylinder is forced to oscillate with a si…
