牵缆浮体在浮力驱动上浮过程中与旋涡的相互作用而引发的舞动是一类典型的非定常涡流与浮体的强耦合作用问题。采用雷诺平均方程求解重叠网格并与悬链线模型相结合，建立水下航行器在尾流中释放牵缆球形浮标的数值模拟模型。模拟了因航行器航行攻角造成的发放尾涡强度、放缆速度造成的牵缆对浮体的束缚效应等形成的旋涡对浮体运动的频谱效应。利用CFD软件，通过控制变量法对放缆速度和攻角对旋涡的影响进行分析，揭示了放缆速度和攻角变化对浮体周围旋涡的影响。
A typical class of unsteady vortex and float strong coupling interaction problems is the gallop induced by the interaction of a towed float with a vortex during buoyancy driven surfacing. By solving the Reynolds mean equation for the overset mesh and combining it with the catenary model, a numerical simulation method for the release of a towed spherical buoy by an underwater vehicle in the wake is established. Simulated are the spectral effects of the vortex on the motion of the float caused by the strength of the release wake vortex caused by the angle of attack and the binding effect of the towline on the float caused by the release speed. The control variable method was used to examine the effects of release speed and angle of attack on the vortex, revealing the effects of changes in release speed and angle of attack on the vortex around the float.
