Abstract
Based on symmetry considerations, Eulerian quantities are defined whic h can serve as diagnostics for the regions of the flow where Lagrangia n chaos is possible in a three-dimensional Navier-Stokes flew. The app licability of the diagnostics is tested in two model flows which are p erturbative solutions of the three-dimensional Navier-Stokes equation: the eccentric Taylor vortex and the (concentric) wavy Taylor vortex.
