随着海洋技术的方展,以及人类对海洋开发的需求,水下无人装备将会有更广泛的应用场景。水下滑翔机是一种无人水下装备,其利用姿态,重心的调整获得动力,完成水下滑翔运动,能量消耗极小,续航时间长,适合大范围、长时间海洋海底探索工作的需求。本文使用OpenFOAM开源CFD库,对某型水下滑翔机机翼在不同安装位置,不同攻角情况下的水动力性能进行数值模拟,给出了其机翼随着位置攻角变化,水下滑翔机的升阻力变化特性,从而为滑翔机设计提供理论参考。同时本文也对流场信息进行深入分析,从机理上解释水下滑翔机水动力特性随机翼状态改变而发生的变化,在设计工作中能够更好地对水下滑翔机外形及机翼布置进行优化。
With the development of marine technology and the demand of human beings, the underwater unmanned equipment will have a wider application scene. The underwater glider is an unmaned underwater equipment, which uses attitude and center of gavity adjustment to obtain power, and completes the underwater glide movement, the energy consuption is very small, and the duration of life is long, which is suitable for the needs of large-range, long-term ocean and submarine exploration. In this paper, using OpenFOAM open source CFD library, the hydrodynamic performance of a certain underwater glider wing at different installation positions and different angle attack is numerically simulated. At the same time, the information of the flow field is analyzed in depth, and the hydrodynamic characteristics of the underwater glider changes with the change of the wing state.
