三维离散矢量场中的涡核识别

Identification of a vortex in 3D discrete vector fields

摘要: 基于临界点理论，使用特征矢量方法在三维离散矢量场中进行了涡核寻找的研究。该方法能够快速准确地找到三维矢量场中的涡核，为CFD工作者提供了一个有效的数据分析工具。搜寻结果与其它方法（如流线法等）进行了比较。

Abstract: Based on the critical poin t theory , this paperuses theeigenvector method to automatically looking for the vortex core in 3D discrete vector fields. This method can find out the vortex core very quickly and accurately, and can give to CFD researchers a v
