Abstract
Most of the vortex identification criteria are based on the kinematics of the flow. In the present work we examine the dynamic terms that are parts of a certain vortex identification criterion in order to decouple the influences of these terms. This methodology is applied to Newtonian and viscoelastic drag-reducing flow in a plane channel.
