The Nature of the Vortex Core

Abstract

The vortex core is a flow region characterised by streamline curvature and uniform vorticity. Continuum theory demands that it be shear free. To be self-consistent thermodynamically, the macroscopic rotation must be accompanied by concomitant internal rotation of the molecules. Kinetic theory of a dilute gas of rotating molecules in a vortex core (that is, subject to local rotation) indicates a polarisation of the internal molecular rotations along the local rotation axis--a Barnett effect. In such a spin-aligned system a very high coefficient of thermal conductivity is predicted, and zero shear and bulk viscosity. Unique optical property is indicated in that although not birefringent the gas would cause the pressure broadening effect in Rayleigh depolarised scattering.
