Numerical Simulation of the Stokes Wave for the Flow around a Ship Hull Coupled with the VOF Model

流动在在水的免费表面附近移动的轮船壳附近产生的表面波浪在这研究数字地被模仿。三维的含蓄的有限体积方法(FVM ) 被使用解决雷纳兹平均海军司烧(RANS ) 方程。可实现的 k-e 骚乱模型被实现了在免费表面地区在轮船壳附近捕获狂暴的流动。方法结合了的液体(VOF ) 的体积 Stokes 波浪理论被用来决定水的免费表面效果。由使用是一自由的六度当模特儿，轮船壳运动数字地一起与 Stokes 波浪被解决。在行动下面司烧海，在空气之间的接口和在一样的常规模式并且那么的水波浪上的波浪做压力和垂直速度。轮船壳搬到象波浪的一样的方法。轮船壳举的振幅是不到波浪高度因为抑制的粘性。这个方法能为轮船运动，波浪和水动力学的学习提供一本重要参考书。

The surface wave generated by flow around a ship hull moving near free surface of water is simulated numerically in this study. The three-dimensional implicit finite volume method （FVM） is applied to solve Reynolds averaged Navier-Stokes （RANS） equation. The realizable k-e turbulence model has been implemented to capture turbulent flow around the ship hull in the free surface zone. The volume of fluid （VOF） method coupled with the Stokes wave theory has been used to determine the free surface effect of water. By using is a six degrees of freedom model, the ship hull＇s movement is numerically solved with the Stokes wave together. Under the action of Stokes waves on the sea, the interface between the air and water waves at the same regular pattem and so does the pressure and the vertical velocity. The ship hull moves in the same way as the wave. The amplitude of the ship hull＇s heave is less than the wave height because of the viscosity damping. This method could provide an important reference for the study of ships＇ movement, wave and hydrodynamics.
