The phase averaging technique was applied to assess the evolution of the coherent waves. By Fourier decomposing the phase averaged data it was possible to obtain the magnitude as wel

Flow topology and properties associated with these points are examined in some detail. While foci and saddle points are associated with maxima of local vorticity and strain rate respectively, nodes are associated

It is shown that two values of surface fractal dimensions correspond to a single spectral power law. Good agree ment with experimental data is obtained for Kolmogorov turbulence.

Large Scale Structure Characterization in a 2D Mixing Layer by Pseudo-Flow-Visualization and DelocalThe main purpose of this paper is to illustrate two particular techniques for Structure Eduction that can be used when the information on flows (velocity, pressure, passive contaminants, etc...) are simultaneously available in several locations. This situation particularly occurs when rakes of sensors are used, or for DNS or LES simulations.
