Inhomogeneous turbulence in the vicinity of a large-scale coherent vortex

We study the statistics of turbulent velocity fluctuations in the neighbour hood of a strong large-scale vortex at large Reynolds number. At integral s cale, the vortex dynamics can be either stable or unstable. We observe that at each distance from the vortex core, the velocity spectrum has a power l aw "inertial range" of scales and that intermittency is also present. The t exture of turbulence is also influenced by the large-scale dynamics of the vortex: as measurements are made closer to the core the spectrum scaling ex ponents, the energy transfert rate (estimated via the third-order structure function) and the intermittency characteristics follow different evolution s in each regime.
