We present an application of the multifractal formalism able to predict the whole shape of the probability density function (pdf) of the dissipative scale, η. We discuss both intense …
Using the multifractal approach, we derive the probability distribution function (PDF) of the velocity gradients in fully developed turbulence. The PDF is given by a nontrivial …
The scaling of acceleration statistics in turbulence is examined by combining data from the literature with new data from well-resolved direct numerical simulations of isotropic …

Using a novel device that enables the real-time measurement of high-order structure functions in turbulence with superior statistical accuracy, we study the shape of the structure …
We consider the Reynolds-number dependence of various higher-order quantities evaluated at a single spatial point in an incompressible turbulent flow. In particular, we …
We present a study of Eulerian and Lagrangian statistics from a high-resolution numerical simulation of isotropic and homogeneous turbulence using the FLASH code, with an …
The phenomenology of velocity statistics in turbulent flows, up to now, relates to different models dealing with either signed or unsigned longitudinal velocity increments, with either …
Inertial-range scaling exponents for both Lagrangian and Eulerian structure functions are obtained from direct numerical simulations of isotropic turbulence in triply periodic domains …

Lagrangian properties obtained from a particle tracking velocimetry experiment in a turbulent flow at intermediate Reynolds number are presented. Accurate sampling of particle …
