A dual resolution phase-field solver for wetting of viscoelastic droplets
Kazem Bazesefidpar, Luca Brandt, Outi Tammisola
We present a new and efficient phase-field solver for viscoelastic fluids with moving contact line based on a dual-resolution strategy. The interface between two immiscible fluids…
Modulation of homogeneous and isotropic turbulence in emulsions
Marco Crialesi-Esposito, Marco Edoardo Rosti, Sergio Chibbaro +1
We present a numerical study of emulsions in homogeneous and isotropic turbulence at . The problem is addressed via Direct Numerical Simulations (DNS), where the Volume o…
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…
Rheology of concentrated suspension of fibers with load dependent friction coefficient
Monsurul Khan, Rishabh V. More, Arash Alizad Banaei +2
We numerically investigate the effects of fiber aspect ratio, roughness, flexibility, and flow inertia on the rheology of concentrated suspensions. We perform direct numerical simu…
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…
Orientation instability of settling spheroids in a linearly density stratified fluid
Rishabh V. More, Mehdi N. Ardekani, Luca Brandt +1
Much work has been done to understand the settling dynamics of spherical particles in a homogeneous and a stratified fluid. However, the effects of shape anisotropy on the settling…
Finite-size evaporating droplets in weakly compressible homogeneous shear turbulence
Nicolò Scapin, Federico Dalla Barba, Giandomenico Lupo +3
We perform interface-resolved simulations of finite-size evaporating droplets in weakly-compressible homogeneous shear turbulence (HST). The study is conducted by varying three dim…
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…
