Buoyant finite-size particles in turbulent duct flow
Sagar Zade, Walter Fornari, Fredrik Lundell +1
Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) have been employed to investigate the dynamics of finite-size spherical particles, slightly heavier than th…
Experimental investigation of turbulent suspensions of spherical particles in a square duct
Sagar Zade, Pedro Costa, Walter Fornari +2
We report experimental observations of turbulent flow with spherical particles in a square duct. Three particle sizes namely: = 40, 16 and 9 ( being the duct full he…
Suspensions of finite-size neutrally-buoyant spheres in turbulent duct flow
Walter Fornari, Hamid Tabaei Kazerooni, Jeanette Hussong +1
We study the turbulent square duct flow of dense suspensions of neutrally-buoyant spherical particles. Direct numerical simulations (DNS) are performed in the range of volume fract…
Clustering and increased settling speed of oblate particles at finite Reynolds number
Walter Fornari, Mehdi Niazi Ardekani, Luca Brandt
We study the settling of rigid oblates in quiescent fluid using interface-resolved Direct Numerical Simulations. In particular, an immersed boundary method is used to account for t…
The effect of polydispersity in a turbulent channel flow laden with finite-size particles
Walter Fornari, Francesco Picano, Luca Brandt
We study turbulent channel flows of monodisperse and polydisperse suspensions of finite-size spheres by means of Direct Numerical Simulations using an immersed boundary method to a…
A numerical approach for particle-vortex interactions based on volume-averaged equations
Toshiaki Fukada, Walter Fornari, Luca Brandt +2
To study the dynamics of particles in turbulence when their sizes are comparable to the smallest eddies in the flow, the Kolmogorov length scale, efficient and accurate numerical m…
Reduced particle settling speed in turbulence
Walter Fornari, Francesco Picano, Gaetano Sardina +1
We study the settling of finite-size rigid spheres in sustained homogeneous isotropic turbulence (HIT) by direct numerical simulations using an immersed boundary method to account…
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…
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…
