Wavelet Cross-Correlation Analysis of Turbulent Mixing from Large-Eddy-Simulations
The complex interactions existing between turbulence and mixing in a bluffbody stabilised flame configuration is investigated by means of a wavelet crosscorrelation analysis on Large Eddy Simulations. The combined approach allows to better point out typical features of unsteady turbulent flows with mixing through the characterisation of the processes involved both in time and scales. The wavele...
متن کاملPlane Turbulent Jet Flow in a Favourable Pressure Gradient
SUMMARY An experimental study has been made of an incompressible turbulent plane jet exhausting downstream into an external flow having a favourable longitudinal pressure gradient approximating that of two-dimensional sink flow. Four flows were studied, for which the ratios of mainstream and jet velocities at the exit plane of the jet were in the range from 0.1 to 0.5. For each case velocity pr...
متن کاملLagrangian statistics across the turbulent-nonturbulent interface in a turbulent plane jet.
Lagrangian statistics from millions of particles are used to study the turbulent entrainment mechanism in a direct numerical simulation of a turbulent plane jet at Re(λ) ≈ 110. The particles (tracers) are initially seeded at the irrotational region of the jet near the turbulent shear layer and are followed as they are drawn into the turbulent region across the turbulent-nonturbulent interface (...
متن کاملCross-correlation Analysis of Wmap and Egret in Wavelet Space
We cross correlate the Wilkinson Microwave Anisotropy Probe (WMAP) first year data and the diffuse gamma-ray intensity maps from the Energetic Gamma Ray Experiment Telescope (EGRET) using spherical wavelet approaches. Correlations at 99.7% significance level have been detected, at scales around 15 in the WMAP foreground cleaned W-band and Q-band maps, based on data from regions that are outside...
متن کاملTurbulence and sound-field POD analysis of a turbulent jet
A Proper Orthogonal Decomposition (POD) is constructed for a Mach 0.9 turbulent jet using a well-validated direct numerical simulation database. Norms are defined based on near-field volume integrals of pressure, turbulence kinetic energy, streamwise velocity, and total enthalpy, two-dimensional integrals of streamswise velocity (to match experimental measurements), and far-field integrals of p...
