摘要
利用ANSYS-CFD软件模拟螺旋侧板(helical strakes)对立管涡激振动的抑制作用。对二维的光滑立管和覆盖两种不同螺旋侧板高程的立管,在不同的雷诺数下进行模拟分析,将得到拖曳力和升力结果与数值和实验结果进行对比表明,螺旋侧板可以影响拖曳力和升力的变化,扰乱流场,很好地抑制漩涡的产生。
The ANSYS-CFD was used to study the efficiency of helical strakes to suppress vortex-induced vibration （VIV）. In the FE analysis, bare riser and two riser models with different height of helical strakes configurations were simulated under different Re number. The numerical results of drag and lift changes with the current speed varied were compared with that of related tests showing that the helical strakes can affect the drag and lift, disturbing the flow field so as to suppressing the VIV.
