【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 study the mechanism of side drift of diversion cable in underwater towing system, based on CFD method, simulation calculation of diversion cable is carried out. The force of guide sleeve is analyzed and solved under the action of heavy buoyancy moment, hydrodynamic moment and friction moment. The lateral force of the guide sleeve and the lateral force produced by the asymmetric flow around the guide sleeve. Combined with the flume test, the results of test and simulation are analyzed, and it is determined that the lateral force caused by the three kinds of torque is the main cause of the drift of the guiding cable. The asymmetry of the guide sleeve is also an important reason for the side drift of the guide cable. Finally, the improvement measures to reduce the side drift of the guide cable are given.
