摘要

为研究水下拖曳系统中导流缆侧漂机理，基于CFD方法，对导流缆进行仿真计算.对导流套进行受力分析，求解在重浮力力矩、流体动力矩和摩擦力力矩作用下,导流套的侧向力以及导流套不对称绕流所产生的侧向力.结合水槽试验，分析试验结果与仿真结果，确定三种力矩作用下引起的侧向力是导流缆侧漂的主要原因.此外，导流套不对称也是导流缆侧漂的重要原因.最后，给出减小导流缆侧漂的改进措施.

Abstract

In order to analyze the kiting mechanism of faired cable for underwater towed system, the numerical simulation was conducted on faired cable based on CFD method. And the force analysis was carried out on fairing, and fairing’s lateral force under the effect of weight moment, buoyancy moment, hydrodynamic torque and friction torque was solved, as well as the lateral force result from asymmetric flow around the fairing. In combination with flume test,simulation result shows that the lateral force caused by the above three torques is the main reason of the kiting of faired cable, in addition, asymmetric fairing also leads to the kiting of faired cable.Finally, the improvement measures for reducing the kiting of faired cable were proposed.

Key words： funderwater towed system; faired cable; fairing; kiting; computational fluid dynamics(CFD)
