Log-Poisson cascade description of turbulent velocity-gradient statistics.
The Log-Poisson phenomenological description of the turbulent energy cascade is evoked to discuss high-order statistics of velocity derivatives and the mapping between their probability distribution functions at different Reynolds numbers. The striking confirmation of theoretical predictions suggests that numerical solutions of the flow obtained at low/moderate Reynolds numbers can play an impo...
متن کاملVelocity Centroids as Tracers of the Turbulent Velocity Statistics
We use the results of magnetohydrodynamic (MHD) simulations to emulate spectroscopic observations and produce maps with variations of velocity centroids to study their scaling properties. In order to assess under which circumstances the scaling properties of the velocity field can be retrieved from velocity centroids, we compare two point statistics of velocity centroids with those of the under...
متن کاملQuantum turbulent velocity statistics and quasiclassical limit.
Two research groups have measured turbulent velocity statistics in superfluid helium using different techniques. The results were in conflict: one experiment revealed Gaussian distributions (as observed in ordinary turbulence), the other experiment determined power laws. To solve the apparent puzzle, we numerically model quantum turbulence as a tangle of vortex filaments, and conclude that ther...
متن کاملSpatial and velocity statistics of inertial particles in turbulent flows
Spatial and velocity statistics of heavy point-like particles in incompressible, homogeneous, and isotropic three-dimensional turbulence is studied by means of direct numerical simulations at two values of the Taylor-scale Reynolds number Reλ ∼ 200 and Reλ ∼ 400, corresponding to resolutions of 512 and 2048 grid points, respectively. Particles Stokes number values range from St ≈ 0.2 to 70. Sta...
متن کاملLagrangian velocity statistics in turbulent flows: effects of dissipation.
We use the multifractal formalism to describe the effects of dissipation on Lagrangian velocity statistics in turbulent flows. We analyze high Reynolds number experiments and direct numerical simulation data. We show that this approach reproduces the shape evolution of velocity increment probability density functions from Gaussian to stretched exponentials as the time lag decreases from integra...
