Abstract

The inadequacy of the use of point-concepts and dynamicconcepts to define a vortex is discussed. An objective and formal kinematic definition of a vortex that corresponds to the basic notion of a swirling motion around a central set of points is proposed. Some results of the application of algorithms based on the proposed definition to the DNS of a flat plate TBL at Re _θ = 670 are presented.
