On the influence of a large scale coherent vortex on the turbulent cascade

On the influence of a large scale coherent vortex on the turbulent cascade

We investigate the flow between coaxial rotating disks in the situation where a strong axial vortex is present over a turbulent background. This is nonstationary and inhomogeneous as is common in most turbulent geophysical flows. We describe the s scale statistics usi...
