提出一种光滑流体动力学数据后处理的三角网格化方法。首先确定流场中每个粒子作用域内的配对粒子集；再以当前粒子的配对粒子集为限定条件进行Delaunay 三角剖分，可得到由粒子作为节点的三角形单元集；最后对“虚假”单元做过滤处理。算例表明复杂边界条件和严重变形的流体区域上的SPH计算结果都可用该方法处理。

A post processing method for smoothed particle hydrodynamics data is presented on basis of Delaunay triangulation. Pairing particle set in scope of each particle in flow field is confirmed, and then discretized by Delaunay triangulation on condition of present pairing particle set, which leads to a set of triangle elements with particles as nodes. At last non material units are filtered. Examples indicate that SPH result with complex boundary conditions and severe deformation of fluid region can be treated.
