本文采用Chakraborty，Balachandar和禤浩焯(2005)的双运动学参数框架(以下简称CBA05)来考虑湍流中的局地涡旋识别问题。总结了各种局部准则之间的相互关系，并将“等效阈值”的概念应用于两种典型的湍流：球面尾迹和槽道流动。利用“等效阈值”提取了非常相似的涡旋结构。
AbstractWe consider local vortex identification in turbulent flows using the two kinematic parameter framework of Chakraborty, Balachandar & Adrian (2005) (hereafter referred to as CBA05). The inter-relationships between the various local criteria are summarized and the notion of ‘equivalent thresholds’ is applied to two canonical turbulent flows: sphere wake and channel flow. Remarkably similar vortex structures are extracted using the ‘equivalent thresholds’.
