Крупномасштабное течение в двумерной турбулентности при статической накачке

Two dimensional turbulence has the striking tendency to self-organize into large-scale, coherent structures due to the inverse energy cascade \cite{67Kra,68Lei,69Bat}. Here we theoretically examine the case of a static pumping where the exciting force is independent of time, the case corresponds to the experimental setup of the works . We establish dependence of the large-scale flow on the system parameters and the pumping characteristics for an unbound system and for a finite box.
