When elasticity affects drop coalescence
PJ Dekker, MA Hack, W Tewes, C Datt, A Bouillant… - Physical review …, 2022 - APS
The breakup and coalescence of drops are elementary topological transitions in interfacial
flows. The breakup of a drop changes dramatically when polymers are added to the fluid …

Evaporation and rheology chart the processability map for centrifugal force spinning
J Merchiers, CDV Martínez Narváez, C Slykas… - …, 2021 - ACS Publications
We show that poly (ethylene oxide)(PEO) solutions formulated using solvent mixtures of
acetonitrile (AcN) and water can be centrifugally spun into fibers. We find that spinnability …

Rapid viscoelastic spreading
A Bouillant, PJ Dekker, MA Hack, JH Snoeijer - Physical Review Fluids, 2022 - APS
We investigate the rapid spreading dynamics of a viscoelastic drop on a solid. Upon contact,
surface tension drives a fast motion of the contact line along the substrate. Here we resolve …

The retraction of jetted slender viscoelastic liquid filaments
Long and slender liquid filaments are produced during inkjet printing, which can
subsequently either retract to form a single droplet, or break up to form a primary droplet and …

Coalescence of bubbles in a viscoelastic liquid
When two bubbles submerged in a liquid are brought closely together, the intermediate
liquid film separating the bubbles begins to drain. Once the film ruptures, the bubbles …
