Multi-scale model of gradient evolution in turbulent flows
Luca Biferale, Laurent Chevillard, Charles Meneveau +1
A multi-scale model for the evolution of the velocity gradient tensor in fully developed turbulence is proposed. The model is based on a coupling between a ``Restricted Euler'' dyn…
Heavy particle concentration in turbulence at dissipative and inertial scales
J. Bec, L. Biferale, M. Cencini +3
Spatial distributions of heavy particles suspended in an incompressible isotropic and homogeneous turbulent flow are investigated by means of high resolution direct numerical simul…
Quantifying microbubble clustering in turbulent flow from single-point measurements
Enrico Calzavarini, Thomas H. van den Berg, Federico Toschi +1
Single-point hot-wire measurements in the bulk of a turbulent channel have been performed in order to detect and quantify the phenomenon of preferential bubble accumulation. We sho…
Lyapunov exponents of heavy particles in turbulence
Jeremie Bec, Luca Biferale, Guido Boffetta +3
Lyapunov exponents of heavy particles and tracers advected by homogeneous and isotropic turbulent flows are investigated by means of direct numerical simulations. For large values…
A mesoscopic approach for multi-phase flows in nano-corrugated channels
R. Benzi, L. Biferale, M. Sbragaglia +2
An approach based on a lattice version of the Boltzmann kinetic equation for describing multi-phase flows in nano- and micro-corrugated devices is proposed. We specialize it to des…
On the effects of vortex trapping on the velocity statistics of tracers and heavy particle in turbulent flows
Jeremie Bec, Luca Biferale, Massimo Cencini +2
The Lagrangian statistics of heavy particles and of fluid tracers transported by a fully developed turbulent flow are investigated by means of high resolution direct numerical simu…
