采用CFD技术数值模拟AUV基于光视觉跟踪探测海底管道运动，分析其水动力性能受海底管道干扰情况。文中数值计算了AUV在无界流的阻力性能，与实验结果符合良好。讨论了AUV处于不同状态、不同位置时，其升力和纵倾力矩性能，分析了AUV在管道及海底耦合干扰下的压力分布，实现了AUV受管道及海底定常水动力干扰性能的预报。结合网格变形技术，数值预报了AUV在过渡区运动过程中的非定常干扰水动力性能。

Hydrodynamic interaction performance between the autonomous underwater vehicle (AUV) and submarine pipeline is forecasted using Computational Fluid Dynamics (CFD) techniques when an AUV is tracking and detecting the submarine pipeline by the light vision .Firstly ,numerical calcula‐tion resistance performance in the unbounded flow has an excellent agreement with the experimental results .And then discussion have been made in its lift and pitch moment performance when an AUV is in different states and locations .The pressure distribution around an AUV has been particularly an‐alyzed by the pipeline and subsea distribution coupled interference .Prediction of steady hydrodynam‐ics interaction performance between an AUV and a pipeline has been achieved .Finally ,numerical cal‐culations of the unsteady interference performance is combined with mesh deformation technique when the AUV is tracking to the pipeline in the transitional zone .
