不同攻角下AUV回收过程中的水动力规律

摘要

通过对AUV(Autonomous Underwater Vehicle)回收过程中运动规律的研究和对纳维—斯托克斯方程(Navier-Stokes equations)及其求解方法的分析,基于CFD(Computational Fluid Dynamics)理论建立了AUV回收运动的三维计算模型,并使用CFD软件完成其物理模型的建立、网格的划分及求解设置.在此基础上对AUV回收过程中的阻力、升力干扰进行分析计算,得到不同攻角下AUV所受到的水动力干扰与AUV和回收平台之间距离的相互联系.%By studying the law of motion of AUV recovery process and analyzing Navier-Stokes equations (Navier-Stokes equations) and its solution.the three-dimensional model of the AUV recovery movement is established based on CFD Theory,and then CFD software is used to finish the build of the physical model,the partition of the mesh and solution set. On this basis, drag and lift interference have been calculated in the process of the AUV recovery. The relationship between AUV hydrodynamic interference suffered by different angle of attack and the distance between recovery platform and AUV is obtained.
