As reduced velocity increase, initial, upper and lower branches have been observed in the oscillation amplitude response for VIV of a smooth cylinder at low values of the mass–damping (Khalak and Williamson...

... of different bionic cylinders. By comparing the results with smooth cylinder, the mechanism of drag reduction for bionic cylinder was discussed. In order to validate the numerical method, a towing experiment was designed to measure the drag under different conditions. The research can provide references...

... limited to map the displacement of the cylinder. The smooth cylinder was tested and used as a reference case. Lastly, the experiment investigated the effects on the cylinder's response of restraining the motion of the test cylinder in the in-line direction. The optimum configuration for the tested round...

The test results for (relatively) smooth cylinders are presented in this paper. INTRODUCTION Vortex-induced vibration (VIV) of cylindrical structures is a fairly well...

... diameter (D), and the dependency of drag coefficient drastically changes at two different KID values of 0.015 (or 0.025) and 0.05. The roughness height at the first turning point of the drag coefficient is almost the same value as the boundary layer thickness of a smooth cylinder which is calculated...
