Simulation and Identification of Organized Vortices in Rotating Turbulent Flowsed by an oscillating grid in a rotating tank. Effects of both rotation and confinement are analyzed, for various Rossby and Reynolds numbers. When the rotation is strong enough, we observe concentrated vortices having axes approximately parallel to the rotation axis. The Fourier- Fourier-Chebyshev p

On the Space-Time Structure of Axisymmetric Rotating Flowson at the rotating lid, the fluid flow is centrifuged toward the cylinder wall, forming a strong vortex core along the axis of the container. Direct numerical simulations and spatio-temporal analysis of the axisymmetric flow are presented here at various Reynolds numbers in the early transition scen

Identification of Coherent Fine Scale Structure in Turbulence have made efforts to establish a theory of fine scale structure by assuming various type of structure as a fine scale structure (Townsend, 1951; Tennekes, 1968; Lundgren, 1982; Pullin and Saffman, 1993; Saffman and Pullin, 1994). Most of them are based on an assumption that many tubelike or sheet-l

Evolution of Vortical Structure in Isotropic Turbulence accordance with the wind-up of vortex sheets, and arrives at its peak after about 10 (initial large-eddy) turnover times for all small kinematic viscosities. The peak value increases almost in inverse proportion to kinematic viscosity, suggesting a singularity at a finite time of enstrophy in the i

Fractal and Spiral Organised Structures: Spectra and Diffusionast decades, mainly because of their occurence in a wide variety of situations. For example, scalar fields rolled-up in a spiral way (Gilbert [2]), or displaying a fractal interface (Nicolleau [6]), are very common features of fluid flows. It has been recently shown that they might have remarkable p
