Turbulent channel flow of dense suspensions of neutrally-buoyant spheres
F. Picano, W. -P. Breugem, L. Brandt
Dense particle suspensions are widely encountered in many applications and in environmental flows. While many previous studies investigate their rheological properties in laminar f…
Numerical simulations of aggregate breakup in bounded and unbounded turbulent flows
Matthaus U. Babler, Luca Biferale, Luca Brandt +8
Breakup of small aggregates in fully developed turbulence is studied by means of direct numerical simulations in a series of typical bounded and unbounded flow configurations, such…
Exact regularized point particle method for multi-phase flows in the two-way coupling regime
P. Gualtieri, F. Picano, G. Sardina +1
Particulate flows have been largely studied under the simplifying assumptions of one-way coupling regime where the disperse phase do not react-back on the carrier fluid. In the con…
Turbulent mixing of a slightly supercritical Van der Waals fluid at Low-Mach number
Francesco Battista, Francesco Picano, Carlo Massimo Casciola
Supercritical fluids near the critical point are characterized by liquid-like densities and gas-like transport properties. These features are purposely exploited in different conte…
Laminar, turbulent and inertial shear-thickening regimes in channel flow of neutrally buoyant particle suspensions
Iman Lashgari, Francesco Picano, Wim-Paul Breugem +1
The aim of this Letter is to characterize the flow regimes of suspensions of finite-size rigid particles in a viscous fluid at finite inertia. We explore the system behavior as fun…
The effect of the Basset history force on particle clustering in Homogeneous and Isotropic Turbulence
Stefano Olivieri, Francesco Picano, Gaetano Sardina +2
We study the effect of the Basset history force on the dynamics of small particles transported in homogeneous and isotropic turbulence and show that this term, often neglected in p…
