| 中文摘要: |
| 为全面确定导流缆在不同情况下的水动力性能,本文对其进行了试验测量研究。设计了一种试验方案,以便同时测出缆在不同攻角时的三组水动力性能数据;同时为消除试验时模型缆有限细长度(展弦比)、近水面效应及水下有效长度的不利影响,进行两组不同长度的模型试验,采用长度差值方法,以得到较为准确的结果。最后,采用数据拟合方法,对试验数据进行处理,给出了无限细长度导流缆在不同攻角、雷诺数时的法向、切向阻力及侧向作用力系数的回归公式,以方便工程应用。 |

| In order to fully determine the hydrodynamic performance of underwater faired cable under different conditions, experimental measurement was carried out. A detailed experimental program was designed, which can obtain three sets of hydrodynamic data simultaneously for an inclined model at different attack angles. At the same time, in order to eliminate the adverse effect from limited aspect ratio, the near free surface effect and the underwater effective length effect, experiments for two sets of similar model but with different length were carried out. The obtained data were processed by length difference method to ensure higher data accuracy. Finally, the experimental data were processed by fitting method and empirical regression formulae of normal, tangential drag coefficient and lateral lift force coefficient of faired cable with infinite aspect ratio and at different attack angles and Reynold numbers are proposed in this paper to facilitate the engineering application. |
