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…

End boundary effects on wakes dynamics of inclined circular cylinders
Kai Zhang, Yan Bao, Dai Zhou +1
We perform direct numerical simulations to characterize the three-dimensional wake dynamics of long inclined circular cylinders with inhomogeneous end boundary conditions. Three Re…
