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)
