Abstract

Two-vortex solutions from the mean field equations respecting all conservation laws of the Euler equations in two dimensions are calculatedin a unit disk. These states are compared to symmetric and off-centersingle-vortex solutions. A thermodynamic stability analysis is used to determine their stability and a critical separation for stable two-vortex states is found from the crossover to instability. This could explain the merging critical ratios observed in numerical simulations and experiments.
