Rheology of dense fiber suspensions: Origin of yield stress, shear thinning and normal stress differences
Monsurul Khan, Rishabh V. More, Luca Brandt +1
We explain the origins of yield stress, shear-thinning, and normal stress differences in rigid fiber suspensions. We investigate the interplay between the hydrodynamic, colloidal a…
The effect of droplet coalescence on drag in turbulent channel flows
Ianto Cannon, Daulet Izbassarov, Outi Tammisola +2
We study the effect of droplet coalescence on turbulent wall-bounded flows, by means of direct numerical simulations. In particular, the volume-of-fluid and front-tracking methods…
Irreversibility and rate dependence in sheared adhesive suspensions
Zhouyang Ge, Raffaella Martone, Luca Brandt +1
Recent experiments report that slowly-sheared noncolloidal particle suspensions can exhibit unexpected rate()-dependent complex viscosities in oscillatory shear, despite a const…
A fully Eulerian hybrid Immersed Boundary-Phase Field Model for contact line dynamics on complex geometries
Armin Shahmardi, Marco Edoardo Rosti, Outi Tammisola +1
We present a fully Eulerian hybrid immersed-boundary/phase-field model to simulate wetting and contact line motion over any arbitrary geometry. The solid wall is described with a v…
A pressure-based diffuse interface method for low-Mach multiphase flows with mass transfer
Andreas D. Demou, Nicoló Scapin, Marica Pelanti +1
This study presents a novel pressure-based methodology for the efficient numerical solution of a four-equation two-phase diffuse interface model. The proposed methodology has the p…
Near-wall turbulence modulation by small inertial particles
Pedro Costa, Luca Brandt, Francesco Picano
We use interface-resolved simulations to study near-wall turbulence modulation by small inertial particles, much denser than the fluid, in dilute/semi-dilute conditions. We conside…
