摘要
本文研究数值模拟含有自由表面的三维非定常流动的表面波动情况。运用部分单元法（partial－celltreatment）的概念成功地处理了各种复杂形状的边界以及复杂的边界条件和流场内部的障碍物，运用VOF（volumeoffluid）方法追踪自由液面。介绍了部分单元法的概念和VOF方法的主要原理，开发了容器中液面非剧烈波动的三维数值模拟程序，并提供了若干个典型工程流动液面波动模型的计算讨论。
In order to simulate the random free surfaces wave of the three dimensional problems with arbitrary boundaries and internal obstacles in engineering, the governing equations of transient flow are introduced by analyzing the solid-liquid two-phase flow model. Furthermore a partial-cell parameter is employed to treat the arbitrary boundary and internal obstacles, which proves to be successful. For free surfaces, a simple but power ful method is described that is based on the concept of a fractional volume of fluid(VOF). This method is shown to be effficient to track complicated free surfaces. A program was developed to simulate the 3-D transient flow with free surface. It also provides some examples of typical surface wave in engineering.
