Interoccurrence time statistics in fully-developed turbulence
Emergent extreme events are a key characteristic of complex dynamical systems. The main tool for detailed and deep understanding of their stochastic dynamics is the statistics of time intervals of extreme events. Analyzing extensive experimental data, we demonstrate that for the velocity time series of fully-developed turbulent flows, generated by (i) a regular grid; (ii) a cylinder; (iii) a fr...
متن کاملIntermittency and scale-dependent statistics in fully developed turbulence.
Fully developed homogeneous isotropic turbulent fields, computed by direct numerical simulation, are compared to divergence-free random fields having the same energy spectrum and either the same helicity spectrum as that of the turbulent data, or vanishing helicity. We show that the scale-dependent velocity flatness quantifies the spatial variability of the energy spectrum. The flatness exhibit...
متن کاملJoint statistics of acceleration and vorticity in fully developed turbulence
We report results from a high resolution numerical study of fluid particles transported by a fully developed turbulent flow at Rλ = 280. Single particle trajectories were followed for a time range spanning more than three decades, from less than a tenth of the Kolmogorov time-scale up to one large-eddy turnover time. We present results concerning acceleration statistics and the statistics of tr...

متن کاملUniversality in fully developed turbulence.
We extend the numerical simulations of She et al. (1993)] of highly turbulent ow with 15 Taylor-Reynolds number Re 200 up to Re 45 000, employing a reduced wave vector set method (introduced earlier) to approximately solve the Navier-Stokes equation. First, also for these extremely high Reynolds numbers Re , the energy spectra as well as the higher moments { when scaled by the spectral intensit...
