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…
The dynamics of a capsule in a wall-bounded oscillating shear flow
LaiLai Zhu, Jean Rabault, Luca Brandt
The motion of an initially spherical capsule in a wall-bounded oscillating shear flow is investigated via an accelerated boundary integral implementation. The neo-Hookean model is…
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…
Particle transport in turbulent curved pipe flow
Azad Noorani, Gaetano Sardina, Luca Brandt +1
Direct numerical simulations (DNS) of particle-laden turbulent flow in straight, mildly curved and strongly bent pipes are performed in which the solid phase is modelled as small h…
