【摘要】：為研究水下拖曳系統(tǒng)中導流纜側(cè)漂機理,基于CFD方法,對導流纜進行仿真計算.對導流套進行受力分析,求解在重浮力力矩、流體動力矩和摩擦力力矩作用下,導流套的側(cè)向力以及導流套不對稱繞流所產(chǎn)生的側(cè)向力.結(jié)合水槽試驗,分析試驗結(jié)果與仿真結(jié)果,確定三種力矩作用下引起的側(cè)向力是導流纜側(cè)漂的主要原因.此外,導流套不對稱也是導流纜側(cè)漂的重要原因.最后,給出減小導流纜側(cè)漂的改進措施.
[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.
