摘要：
Based on the bionics study on trailing-edge serrations of some birds, a vortex-induced vibration suppression device for marine risers was put forward with double bird-wing shaped streamers. The water flow simulation experiment was performed on the model of a bare cylinder model and cylinder models with different trailing edge profiles and different lengths of streamers, and the wake flow field of the model was measured using the particle image velocimetry. By comparing the corresponding wake streamline diagrams and vorticity diagrams, the following conclusions were found. The double streamers structure can effectively reduce the vortex behind the cylindrical model in the water flow, and the trailing edge profiles of streamers can affect the flow field around the cylinder. When using trailing edge serrated streamers, the generation of vortex will lag. When the length of the streamers are about four times the diameter of the cylinder, the effect of vortex suppressing is better. Therefore, the bird-wing shaped vortex-induced vibration suppression device for risers is efficient and of good working performance. © 2020, Editorial Office of Journal of Vibration and Shock.
