... of the cylinder increases gradually with the increase of the swing angle. With the increase of swing-to-rotate ratio, the distance of the lag and forward movement of the separation point on the upper and lower surfaces of the cylinder, the angle between the vortex shedding and the horizontal direction increases...

... and the transverse street regime. Results of vortex evolution, flow regimes and hydrodynamic force coefficients are compared. INTRODUCTION In actual production, offshore floating structures subject to waves, currents or winds will cause the platform to move periodically in the water. Then relatively oscillatory...

... by vortex-induced vibration (VIV) when the reduced velocity is smaller than the critical reduced velocity and by galloping when the reduced velocity is larger than the critical reduced velocity. When the spacing ratio is 3.5, only VIV occurs for V r is less than 20 while a response with combination...

... is considered and the Re is defined, U DRe , (1) where is the kinematic viscosity of the fluid and U is the undisturbed fluid velocity. A constant Re was considered because both the force coefficients and the vortex shedding frequency are relatively independent of Re in subcritical flow regime (Bearman...

... platforms. Due to the strong engineering application background, hydro-/aerodynamics associated with slender structures have been widely researched. The flow around an isolated cylinder involves most of the generic flow features (flow separation, vortex shedding, recirculation, transition of turbulence...

... forces and vortex shedding frequency. Introduction Vortex induced vibration (VIV) takes place when a fluid flow passes an elastically mounted bluff body. Earlier studies of VIV focused primarily on the suppression of this phenomenon to minimize its damage caused to engineering structures...

INTRODUCTION Oscillatory flow around a cylindrical structure is of importance due to its intrinsic interest in theoretical...

... on the Reynolds number, has been known to show diverse flow characteristics such as the axi-symmetric flow, and irregular rotation of separation points, unsteady flows, periodic vortex shedding, etc. A sphere is considered as an idealized model of three-dimensional axisymmetric bluff bodies. For engineering...
