Self-similar Structures in 2-D Turbulence: Experimental and Theoretical Study of Vortex Multipoles

Conference paper

Abstract

Experimental evidence for dipole-like vortex structures in turbulence affected by body forces in a stratified fluid is given. The results from an experimental investigation into the dynamics of the interactions between vortex dipoles and also between vortex dipoles and a vertical barrier are presented. Theoretical consideration reveals that the result of interaction is determined by two main governing parameters: dipolar (J) and quadrupolar (Q) vorticity distributions of the flow. The connection between J, Q and forces applied to the viscous fluid is obtained and a self-similar solution for a vortex quadrupole is found.
