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...

| Summary: | 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 using tools recently introduced for homogeneous turbulent flows. It seems that the cascade cess is preserved although modified by the large coherent structure. |
