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…
Generalized Lattice Boltzmann Method with multi-range pseudo-potential
M. Sbragaglia, R. Benzi, L. Biferale +3
The physical behaviour of a class of mesoscopic models for multiphase flows is analyzed in details near interfaces. In particular, an extended pseudo-potential method is developed,…
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…
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…
Mesoscopic modeling of a two-phase flow in the presence of boundaries: the Contact Angle
R. Benzi, L. Biferale, M. Sbragaglia +2
We present a mesoscopic model, based on the Boltzmann Equation, for the interaction between a solid wall and a non-ideal fluid. We present an analytic derivation of the contact ang…
On the Anomalous Scaling Exponents in Nonlinear Models of Turbulence
Luiza Angheluta, Roberto Benzi, Luca Biferale +2
We propose a new approach to the old-standing problem of the anomaly of the scaling exponents of nonlinear models of turbulence. We achieve this by constructing, for any given nonl…
Dynamics and statistics of heavy particles in turbulent flows
M. Cencini, J. Bec, L. Biferale +5
We present the results of Direct Numerical Simulations (DNS) of turbulent flows seeded with millions of passive inertial particles. The maximum Taylor's Reynolds number is around 2…
