Abstract:
The existing approaches to analyzing the dynamics of coherent vortex structures are considered from the viewpoint of the calculus of variations for Poisson systems. For turbulent hydrodynamic flows with large-scale vortices, a simulation technique in the form of statistical mechanics of the Euler equation in a “coarse-grained” representation is substantiated.
Key words:
Lynden–Bell distribution, coherent structures, Onsager vortices, Joyce–Montgomery equation, variational principles, turbulent flows.
