Profile of a coherent vortex in twodimensional turbulence at static pumping
Abstract
We examine the velocity profile of coherent vortices appearing as a consequence of the inverse cascade of twodimensional turbulence in a finite box in the case of static pumping. We demonstrate that in the passive regime the flat velocity profile is realized, as in the case of pumping short correlated in time. However, in the static case the energy flux to large scales is dependent on the system parameters. We demonstrate that it is proportional to $f^{4/3}$ where $f$ is the characteristic force exciting turbulence.
