摘　　要：三维实体建模是进行CFD(计算流体力学)计算的前提和基础。对同一实体,不同造型方法下生成的三维实体模型有着不同的几何信息和拓扑信息。本文从计算机图形学的角度,介绍了复杂几何实体的三维造型方法及其原理,并在此基础上,以离心泵蜗壳为例,分析了不同实体造型方法对CFD计算结果的影响。Different formative methods are adopted to sculpt entity model of a same volute in Pro/E,and the models are meshed.Through comparing and analyzing meshes numbers and meshes quality of different models,the influence of different methods which uses to build volute's entity models on CFD computational mesh is opened out.At the same time,reasons of the influence are analyzed from angle of computer graphics knowledge.The research will provide some references for CFD computation in stabilization,precision,efficiency and mesh's quality,etc.
