The effect of particle density in turbulent channel flow laden with finite size particles in semi-dilute conditions
Walter Fornari, Alberto Formenti, Francesco Picano +1
We study the effect of varying the mass and volume fraction of a suspension of rigid spheres dispersed in a turbulent channel flow. We performed several Direct Numerical Simulation…
Rheology of confined non-Brownian suspensions
Walter Fornari, Luca Brandt, Pinaki Chaudhuri +3
We study the rheology of confined suspensions of neutrally buoyant rigid monodisperse spheres in plane-Couette flow using Direct Numerical Simulations. We find that if the width of…
Channel flow of rigid sphere suspensions: particle dynamics in the inertial regime
Iman Lashgari, Francesco Picano, Wim Paul Breugem +1
We consider suspensions of neutrally-buoyant finite-size rigid spherical particles in channel flow and investigate the relation between the particle dynamics and the mean bulk beha…
Sedimentation of finite-size spheres in quiescent and turbulent environments
Walter Fornari, Francesco Picano, Luca Brandt
Sedimentation of a dispersed solid phase is widely encountered in applications and environmental flows, yet little is known about the behavior of finite-size particles in homogeneo…
Transition and self-sustained turbulence in dilute suspensions of finite-size particles
Iman Lashgari, Francesco Picano, Luca Brandt
We study the transition to turbulence of channel flow of finite-size particle suspensions at low volume fraction, i.e. . The critical Reynolds number above which tu…
Continuous growth of droplet size variance due to condensation in turbulent clouds
Gaetano Sardina, Francesco Picano, Luca Brandt +1
We use a stochastic model and direct numerical simulation to study the impact of turbulence on cloud droplet growth by condensation. We show that the variance of the droplet size d…
