摘要

为了研究螺旋侧板对立管涡激振动的抑制作用，采用模型试验的方法对光滑立管以及3组带程螺旋侧板的立管在不同雷诺数下进行了两向涡激振动试验研究，比较分析了光滑立管与带螺旋侧板立管的两向涡激振动响应差异，同时还研究了螺旋侧板导程对立管两向涡激振动的影响。采用示踪方法对4组立管模型涡激振动时的尾流进行了观测。研究结果表明：螺旋侧板能扰乱立管尾流的涡旋泄放，能有效抑制立管横流向的振动响应，同光滑立管相比，带螺旋侧板立管的横流向振动响应减小幅度可达70%左右，但顺流向的振动响应有所增加；9D导程的螺旋侧板对立管的涡激振动抑制效果最好；同带螺旋侧板的3组立管相比，光滑立管的斯托哈尔数在各雷诺数情况下普遍要大一些。

Abstract

In order to study suppression effect of helical strakes on risers’VIV,model test method was used to conduct tests for VIV of 2-DOF risers including one bare riser and 3 risers with helical strakes of different pitches under different Reynolds numbers in a water channel. VIV differences among the bare riser and 3 risers with helical strakes were analyzed,and the effects of different helical pitches on risers’VIV were studied. Moreover,wake flows of these 4 risers during their VIV were observed with the tracer method. The results showed that helical strakes can disturb risers wake flows’vortex discharge to effectively suppress risers vibration responses in their transverse flow direction; compared to the bare riser,vibration responses in transverse flow direction of risers with helical strakes can be reduced by 70 percent,but their in-line vibration responses increase; the helical strake with a 9D pitch has the best suppressing effect on risers’VIV; Strouhal number of the bare riser is larger than those of risers with helical strakes under different Reynolds numbers.
