摘要
随着船舶速度的提高,将会带来兴波阻力增加和船体振动加剧等问题。在各种
减小高速航行状态下兴波阻力的措施中,给船舶加装水翼是一个应用极为广泛而且
十分有效的手段。船用翼为提高船速、增强船舶耐波性与适航性等发挥了巨大的作
用。因此水翼的水动力性能研究就具有重要的意义。
本文对船用翼的发展历程进行了回顾,对流体力学中常用的数值方法有限元法、
有限体积法、涡格法进行了概述,同时还介绍了基于格林定理的面元法的一种新的计
算水翼水动力性能的计算模型。另外为了进一步研究扑翼的水动力性能,本文还对扑
翼的试验装置进行了设计,进行了水池试验。
本文的主要工作是针对水翼在无限流域中运动时受力情况进行的分析,发展了一
种求解二维水翼定常绕流问题的计算模型,即本文所用的基于格林定理的面元法。本
文以格林定理为基础,在物体边界上分布源汇和偶极子,发展了一种数值求解二维水
翼定常绕流问题的计算模型。该方法以物面速度势为未知量进行求解,然后通过插值
计算得到速度分布,进而利用伯努利积分得到水翼的压力分布和相关水动力性能参
数,整个计算采用 C 语言程序实现。另外本文针对研究内容设计了试验装置,并在
三维软件 Solidworks 中对该装置进行了仿真研究。
本文分别对无升力的二维圆柱绕流和有升力的二维水翼进行了计算。通过数值计
算结果与试验数据和相关理论解析解的比较分析,证实了本方法的可行性和可靠性。

Abstract
With increasing of the ship speed, it will causing the increase of wave
resistance,and the deterioration of the hull vibration problem. In the various measures to
reduce the wave resistance of high-speed ship, it is a very extensive and effective facility
to install Hydrofoil on the ships. The hydrofoil for improve the speed, enhance the ship
seakeeping and sea-keeping capacity has played a tremendous role. Therefore studying
hydrodynamic performance of the hydrofoil has important significance.
The development of hydrofoil has been reviewed in this dissertation, including the
Finite Element Method, Finite Volume Method, Vortex Lattice Method, as well as its
application in engineering. It also gives a brief introduction of one putation
model Based on Green’s theorem, In addition to further study Flapping-Wing
hydrodynamic performance, we also designed the test device, and the eed in the test.
The main task focuses on the analysis of the movement of hydrofoil in infinite deep,
putation model is reduced to solve the problem of steady flow around a
two-dimensional hydrofoil by distribute sources and sinks and dipole at the border. We
take surface velocity potential for unknowns to so
