Two-dimensional turbulent flows accomplish local convection of the energy

As new experiments confirmed, two-dimensional turbulent motion accomplishes local convection of energy. This makes it possible to more deeply understand the dynamics of the models of the atmosphere and liquids. 2d flows are in many respects similar to the behavior of Bose-Einstein condensate. The fact is that vortices in such systems can organize themselves and interact with coherent method. Is possible, the best manifestation of this sequence - “return cascade” the effect: small turbulences grow together into the large vortex. This effect partially contributes to shaping of the large-scale regions of convection in the atmosphere, which can be examined by 2d liquid. Reverse- cascade process could continue unlimitedly to [iekh] perspiration, until entire liquid wholly is implicated into the vortex, if scattering the substantial part of the energy was not considered. Researchers were not assured that energy, first of all, departs to the exchange of pulse (viscosity) on Wednesday. At The [pittsburgskiy] university the group of researchers with the aid of the magnetic and electric field simulated [turbelentnye] processes in the soap film on the salt basis. Adding a little lycopodium (fungus disputes) into the film, they observed the motion of spores. It was explained that interaction with air had in the worst case clout on the dissipation of energy, than than viscous friction. These experiments will make it possible more objectively to explain the energy transfer in the turbulent 2d liquids. However, it is worthwhile to note, actually that there are no such systems, where interaction occurs [isklyuchitalno] in two measurements, but often there is so that the third measurement it supports the steady state of two-dimensional motion.
