Acceleration statistics of heavy particles in turbulence

- J. Bec, Luca Biferale,
+5 authors F. Toschi - PhysicsJournal of Fluid Mechanics
- 5 August 2005

We present the results of direct numerical simulations of heavy particle transport in homogeneous, isotropic, fully developed turbulence, up to resolution $512^3$ ($R_\lambda\approx 185$). Following… Expand

Heavy particle concentration in turbulence at dissipative and inertial scales.

- J. Bec, Luca Biferale, M. Cencini, A. Lanotte, S. Musacchio, F. Toschi
- PhysicsPhysical review letters
- 18 August 2006

Spatial distributions of heavy particles suspended in an incompressible isotropic and homogeneous turbulent flow are investigated by means of high resolution direct numerical simulations. In the… Expand

Lagrangian Properties of Particles in Turbulence

- F. Toschi, E. Bodenschatz
- Physics
- 2009

The Lagrangian description of turbulence is characterized by a unique conceptual simplicity and by an immediate connection with the physics of dispersion and mixing. In this article, we report some… Expand

Shear-improved Smagorinsky model for large-eddy simulation of wall-bounded turbulent flows

- E. Lévêque, F. Toschi, L. Shao, J. Bertoglio
- Physics, Environmental ScienceJournal of Fluid Mechanics
- 30 May 2006

A shear-improved Smagorinsky model is introduced based on results concerning mean-shear effects in wall-bounded turbulence. The Smagorinsky eddy-viscosity is modified as vT =(Csδ)2(|S|—|〈S〉|): the… Expand

Intermittency in the velocity distribution of heavy particles in turbulence

- J. Bec, Luca Biferale, M. Cencini, A. Lanotte, F. Toschi
- PhysicsJournal of Fluid Mechanics
- 1 March 2010

The statistics of velocity differences between pairs of heavy inertial point particles suspended in an incompressible turbulent flow is studied and found to be extremely intermittent. The problem is… Expand

Lagrangian statistics of particle pairs in homogeneous isotropic turbulence

- Luca Biferale, G. Boffetta, A. Celani, B. Devenish, A. Lanotte, F. Toschi
- Physics, Environmental Science
- 31 January 2005

We present a detailed investigation of the particle pair separation process in homogeneous isotropic turbulence. We use data from direct numerical simulations up to R280 following the evolution of… Expand

Cloud Droplet Growth by Condensation in Homogeneous Isotropic Turbulence

- A. Lanotte, A. Seminara, F. Toschi
- Physics, Environmental Science
- 1 June 2009

The growth of cloud droplets by diffusion of water vapor in a three-dimensional homogeneous isotropic turbulent flow is considered. Within a simple model of advection and condensation, the dynamics… Expand
