On the velocity distribution in homogeneous isotropic turbulence: correlations and deviations from Gaussianity
homogeneous isotropic turbulence deviations Gaussianity Fluid Dynamics
2011/8/1
Abstract: We investigate the single-point probability density function of the velocity in three-dimensional stationary and decaying homogeneous isotropic turbulence. To this end we apply the statistic...
Dependence of decaying homogeneous isotropic turbulence on initial conditions

We conduct a careful analysis of the data provided by Krogstad & Davidson (2011) and show that their data do not support their conclusions. According to their published data, their decaying approximat...

ordinary hydrodynamics, u2(t) / t−6/5, is used as input in FRW equations in order to investigate ...
DNS-based measurement of the mean impulse response of homogeneous isotropic turbulence
DNS-based measurement impulse response isotropic turbulence
2010/11/16
A technique for measuring the mean impulse response function of stationary homogeneous isotropic turbulence is proposed. Such measurement is carried out here on the basis of Direct Numerical Simulati...
