Abstract

The effect of diffusion anisotropy of material particles in toroidal vortices (TVs) is experimentally studied in plasma TVs in air, in vortex rings in air and water. The essence of this effect consists in the fact that diffusion coefficients of material particles in TVs in the direction perpendicular to the rotation axis D ⊥ are much lower than in the direction parallel to this axis D ‖. The coefficient D ⊥ is determined for propane molecules in air TVs, and the dependence of the coefficient D ⊥ of ink particles in water TVs on the rotation angular velocity ω is studied. It is shown that the coefficient D ⊥ can decrease with increasing ω by a factor of 10–25 in comparison with the coefficient D ‖.
