Emulsions in microfluidic channels with asymmetric boundary conditions and directional surface roughness: stress and rheology
Francesca Pelusi, Daniele Filippi, Ladislav Derzsi +2
The flow of emulsions in confined microfluidic channels is affected by surface roughness. Directional roughness effects have recently been reported in channels with asymmetric boun…
Fluidization and wall slip of soft-glassy materials by controlled surface roughness
Ladislav Derzsi, Daniele Filippi, Giampaolo Mistura +5
The motion of soft-glassy materials (SGM) in a confined geometry is strongly impacted by surface roughness. However, the effect of the spatial distribution of the roughness remains…
Stretching of viscoelastic drops by steady sliding
Silvia Varagnolo, Daniele Filippi, Giampaolo Mistura +2
The sliding of non-Newtonian drops down planar surfaces results in a complex, entangled balance between interfacial forces and non linear viscous dissipation, which has been scarce…
Deviation of viscous drops at chemical steps
Ciro Semprebon, Silvia Varagnolo, Daniele Filippi +4
We present systematic wetting experiments and numerical simulations of gravity driven liquid drops sliding on a plane substrate decorated with a linear chemical step. Surprisingly,…
