| 摘 要： | 研究了深海海底悬跨管道安装水平方向扰流器。计算分析了层流状态下管道与海床壁面间隙分别为不同间隙比时管道层流区绕流流场及振动特征的变化情况,并与未安装扰流器的悬跨管道进行对比分析评价水平扰流器对海底悬跨管道振动抑制效果。此外,还探讨分析了不同结构尺寸的扰流器对管道振动抑制效果。

| Abstract: | The horizontal spoiler is fixed on the suspended pipe in the deep seabed. The change of flow and vibration are analyzed in the laminar when the clearances between the pipeline and seabed are different. Compared with the spanning pipeline without the spoiler, the effects of vibration abatement depressed of pipeline with the horizontal spoiler are evaluated. Moreover, the paper also discusses the effect of the vibration abatement of pipeline with the different sizes of spoiler. |
