Numerical Simulation of Unsteady Hydrodynamic in the Process of Underwater UUV Docking

College of Marine Engineering, Northwestern Polytechnical University, Xi′an 710072, China

摘要

摘要: UUV水下对接回收过程中, 回收装置和UUV之间存在非定常流体干扰现象。采用有限体积法和非结构动网格技术, 运用SIMPLEC算法及k-ε湍流模型, 在笛卡尔坐标系下对UUV水下对接过程进行数值模拟, 并得到不同速度和攻角下, UUV流体动力随距离的变化规律及相应流场分布。通过UUV与远场实验值进行对比分析, 验证了基于动网格技术的有限体积法在处理UUV水下对接过程中流体干扰问题的可行性。

Abstract: During the docking recovery process of unmanned underwater vehicle(UUV), unsteady hydrodynamic interference occurs between the recovery device and UUV. In this study, the finite volume method (FVM) and the dynamic unstructured mesh technique were used to simulate the docking process of UUV. SIMPLEC algorithm and k-ε model in the Descartes coordinates were also adopted. The rules of hydrodynamic versus distance and the relative distribution of pressure field at different velocity and angle of attack were obtained. By comparing the UUV simulation results with the trial ones in far field, the feasibility of the FVM based on dynamic mash technique in dealing with hydrodynamic interference was verified in the process of UUV docking.
