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,…
Sliding droplets of Xanthan solutions: a joint experimental and numerical study
Silvia Varagnolo, Giampaolo Mistura, Matteo Pierno +1
We have investigated the sliding of droplets made of solutions of Xanthan, a stiff rodlike polysaccharide exhibiting a non-newtonian behavior, notably characterized by a shear-rate…
Sliding drops across alternating hydrophobic and hydrophilic stripes
M. Sbragaglia, L. Biferale, G. Amati +4
We perform a joint numerical and experimental study to sistematically characterize the motion of drops sliding over a periodic array of alternating hydrophobic and hydrophilic stri…
Stick-Slip Sliding of Water Drops on Chemically Heterogeneous Surfaces
Silvia Varagnolo, Davide Ferraro, Paolo Fantinel +5
We present a comprehensive study of water drops sliding down chemically heterogeneous surfaces formed by a periodic pattern of alternating hydrophobic and hydrophilic stripes. Drop…
