On the possibility of collective vortex motion in liquids

It is shown that a model system of random walk of particles with superimposed vortex motion simulates the specific behaviors of a two-particle correlation function DP ( t ) = 〈[ r i ( t ) - r i (0)]•[ r k ( t ) - r k (0)]〉, which are observed in molecular dynamics models of water and liquid argon.

Summary:It is shown that a model system of random walk of particles with superimposed vortex motion simulates the specific behaviors of a two-particle correlation function DP ( t ) = 〈[ r i ( t ) - r i (0)]•[ r k ( t ) - r k (0)]〉, which are observed in molecular dynamics models of water and liquid argon. Hence, in liquids there well may be mesoscopic-sized vortices (of the order of ten intermolecular distances).
