Motion of an elastic capsule in a constricted microchannel
Cecilia Rorai, Antoine Touchard, Lailai Zhu +1
We study the motion of an elastic capsule through a microchannel characterized by a localized constriction. We consider a capsule with a stress-free spherical shape and impose its…
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…
The motion of a deforming capsule through a corner
Lailai Zhu, Luca Brandt
A three-dimensional deformable capsule convected through a square duct with a corner is studied via numerical simulations. We develop an accelerated boundary integral implementatio…
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…
The lift-up effect: the linear mechanism behind transition and turbulence in shear flows
Luca Brandt
The formation and amplification of streamwise velocity perturbations induced by cross-stream disturbances is ubiquitous in shear flows. This disturbance growth mechanism, so neatly…
A microfluidic device to sort capsules by deformability: A numerical study
Lailai Zhu, Cecilia Rorai, Dhrubaditya Mitra +1
Guided by extensive numerical simulations, we propose a microfluidic device that can sort elastic capsules by their deformability. The device consists of a duct embedded with a sem…
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…
