Abstract

Vortex which is a classical flow pattern has not a strict mathematical definition so far, and vortex identification is still an important approach to distinguish them. Different vortex identifications and physical meaning are summarized in this paper as well as the Q and λ 2 identifications are employed to distinguish the actual various vortices in the cavity and analyze the topologic structure of vortices, the good results are obtained.
