Suspensions of non-Brownian rods: droplet pinch-off, onset of heterogeneity and effective extensional viscosity
Virgile Thiévenaz, Nathan Vani, Alban Sauret
The stretching and pinch-off of a liquid bridge is a simple way to probe when a suspension of particles stops behaving as a continuum. In this study, we consider density-matched su…
Impact of viscoelastic polymer solution droplets on a granular bed
Jooyeon Park, Theophile Meiller, Sreeram Rajesh +1
The impact of polymer solution droplets on granular beds is relevant to powder processing, binder jetting additive manufacturing, and environmental applications involving erosion c…
Axial forces in capillary liquid bridges of polymer solutions
Sreeram Rajesh, Riley S. Tinianov, Jooyeon Park +1
Liquid bridges form between particles during wet mixing with binders or by condensation due to ambient humidity. The consequences of capillary bridges can be quite drastic, creatin…
Impact and spreading dynamics of a drop of fiber suspension on a solid substrate
Sreeram Rajesh, Alban Sauret
The presence of non-Brownian spherical particles dispersed in a liquid modifies the impact and spreading dynamics of a drop on a hydrophilic substrate. This difference in spreading…
Experimental models for cohesive granular materials: a review
Ram Sudhir Sharma, Alban Sauret
Granular materials are involved in most industrial and environmental processes, as well as many civil engineering applications. Although significant advances have been made in unde…
On the shape of air bubbles trapped in ice
Virgile Thiévenaz, Jochem G. Meijer, Detlef Lohse +1
Water usually contains dissolved gases, and because freezing is a purifying process these gases must be expelled for ice to form. Bubbles appear at the freezing front and are then…
