... Abstract The flow around a circular cylinder at Reynolds numbers near the drag crisis was numerically simulated based on a dynamic Smagorinsky Large Eddy Simulation (LES) model at two Reynolds of Re = 1.0 × 10 5 and 6.0 × 10 5 . The flow structures and the hydrodynamic force on the cylinder...

.... Although some researchers (Cai et al., 2008; Song et al., 2011; Xie et al., 2011) used numerical simulation to discuss the responses between ISWs and the small vertical cylinder, they almost simplified the problem and did not discuss the turbulent effect. In order to further study the 3D interaction...
