Superstatistics as the statistics of quasi-equilibrium states: Application to fully developed turbulence
Superstatistics quasi-equilibrium states developed turbulence
2011/8/18
Abstract: In non-equilibrium states, currents are produced by irreversible processes that take a system toward the equilibrium state, where the current vanishes. We demonstrate, in a general setting, ...
Statistics of the Energy Dissipation Rate and Local Enstrophy in Turbulent Channel Flow
Turbulent channel flows, turbulent shear flows, energy dissipation rate, enstrophy
2011/9/6
Using high-resolution direct numerical simulations, the height and Reynolds number dependence of higher-order statistics of the energy dissipation rate and local enstrophy are examined in incompressib...
Exact Fidelity and Full Fidelity Statistics in Regular and Chaotic Surroundings
Chaotic Surroundings coupling coefficients
2010/4/7
For a prepared state exact expressions for the time dependent mean fidelity as well as for the mean inverse paricipation ratio are obtained analytically. The distribution function of fidelity in the l...
MEASUREMENTS OF HIGHER-ORDER TURBULENT STATISTICS IN A TURBULENT BOUNDARY LAYER SUBJECTED TO A SHORT ROUGHNESS STRIP

2009/10/14
Hot-wire measurements have been undertaken in a turbulent boundary layer which is subjected to an impulse in form of a short roughness strip with the aim of determining its effect on turbulence struct...
