摘要
通过改进流体体积法 (VOF)方程求解部分 ,提高了离散模型中表面单元和液体内部对流的精度 ,从而在整体上减小了对流产生的体积误差 ;为逼真地展现具有复杂表面的运动液体场景 ,提出一种基于几何搜索的表面重建方法———种子-绕空方法 该方法可以将VOF方法生成的带缝隙表面用C0 连接的三角面片集表示 ,以获得光滑连续的液面表示
In order to realistically simulate fluid flows, we first improved the solution procedure of the volume of fluid (VOF) method and more precise advection of fluid cells, including the surface and inner cells, was obtained Volume errors are reduced largely on the whole A novel surface reconstruction approach, called the 'seed round empty' scheme, regarding the strategy of geometrical search was set forth The fluid surface generally containing gaps in VOF method is now represented as a set of triangle pieces connected with C 0 continuity Examples illustrate realistic liquid scenes with smooth surface on relatively coarse grids
