Coherent Structure Eduction in Wavelet-forced Two-dimensional Turbulent Flows
We analyze vorticity fields obtained from direct numerical simulations (DNS) of statistically stationary two-dimensional turbulence where the forcing is done in wavelet space. We introduce a new eduction method for extracting coherent structures from two-dimensional turbulent flows. Using a nonlinear wavelet technique based on an objective universal threshold we separate the vorticity field int...
متن کاملExtraction of a Multiscale Structure of a Turbulent Lobed Jet from PIV Results Using a Vector Wavelet Multiresolution Technique
The wavelet-based vector multiresolution technique was applied to the postprocessing of PIV results for identifying the multiscale turbulent structures of a lobed jet. By analyzing the instantaneous streamlines and vorticity fields of various scales, we obtained important information on the multiscale flow structures. The large-scale vortices or coherent structures with a central scale of a = 1...
متن کاملA. Spectrum of Coherent Light Scattered from a Turbulent Jet
The work of our group is being carried out as a cooperative effort with Giorgio Fiocco, of the European Space Research Institute (ESRIN), Frascati, Italy. For the most part, this research is directed toward problems of interest in the atmospheric sciences. In particular, we have conducted spectral analyses of the light scattered from a laser beam by atmospheric molecules and aerosols, using a F...
متن کاملWavelet multiresolution analysis of the three vorticity components in a turbulent far wake.
The main objective of the present study is to examine the characteristics of the vortical structures in a turbulent far wake using the wavelet multiresolution technique by decomposing the vorticity into a number of orthogonal wavelet components based on different central frequencies. The three vorticity components were measured simultaneously using an eight-wire probe at three Reynolds numbers,...
