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 role of wetting on the flow of two immiscible fluids in porous media
Armin Shahmardi, Salar Zamani Salimi, Outi Tammisola +2
We study the role of the capillary number, and of the surface wettability on the dynamics of the interface between an invading and a defending phase in a porous medium by mean…
Viscoelasticity of suspension of red blood cells under oscillatory shear flow
Naoki Takeishi, Marco Edoardo Rosti, Naoto Yokoyama +1
We present a numerical analysis of the rheology of a suspension of red blood cells (RBCs) for different volume fractions in a wall-bounded, effectively inertialess, small amplitude…
The interaction of droplet dynamics and turbulence cascade
Marco Crialesi-Esposito, Sergio Chibbaro, Luca Brandt
The dynamics of droplet fragmentation in turbulence is described in the Kolmogorov-Hinze framework. Yet, a quantitative theory is lacking at higher concentrations when strong inter…
Experimental and numerical investigation of bubble migration in shear flow: deformability-driven chaining and repulsion
Blandine Feneuil, Kazi Tassawar Iqbal, Atle Jensen +3
We study the interaction-induced migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organise into chains aligned in the flow dire…
Evaporating Rayleigh-Bénard convection: prediction of interface temperature and global heat transfer modulation
Nicoló Scapin, Andreas D. Demou, Luca Brandt
We propose an analytical model to estimate the interface temperature and the Nusselt number for an evaporating two-layer Rayleigh-Bénard configuration in statistically s…
FluTAS: A GPU-accelerated finite difference code for multiphase flows
Marco Crialesi-Esposito, Nicolo Scapin, Andreas D. Demou +4
We present the Fluid Transport Accelerated Solver, FluTAS, a scalable GPU code for multiphase flows with thermal effects. The code solves the incompressible Navier-Stokes equation…
Numerical simulation of the coalescence-induced polymeric droplet jumping on superhydrophobic surfaces
Kazem Bazesefidpar, Luca Brandt, Outi Tammisola
Self-propelled jumping of two polymeric droplets on superhydrophobic surfaces is investigated by three-dimensional direct numerical simulations. Two identical droplets of a viscoel…
