Pressure and asymmetry govern the shape and stiffness of inflatables
Nathan Vani, Tom Joblin, Alejandro Ibarra +3
Inflatables made of thin sheets constitute a lightweight, scalable alternative to conventional soft robots. Since sheets are essentially inextensible while offering low resistance…
A single length scale rules ballistic aggregation: travels of a droplet train
Nathan Vani, Stefan Kooij, Aritro Mukherjee +3
Ballistic aggregation is a canonical non-equilibrium process, relevant across scales from granular gases to planetary accretion. Collisions are driven by differences in velocities,…
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…
Asymmetric Bending Boundary Layer: the -test
Nathan Vani, Alejandro Ibarra, José Bico +2
We investigate the mechanics of two asymmetric ribbons bound at one end and pulled apart at the other ends. We characterize the elastic junction near the bonding and conceptualize…
Role of the constriction angle on the clogging by bridging of suspensions of particles
Nathan Vani, Sacha Escudier, Deok-Hoon Jeong +1
Confined flows of particles can lead to clogging, and therefore failure, of various fluidic systems across many applications. As a result, design guidelines need to be developed to…
Caging and fluid deformations in dense bidisperse suspensions
Virgile Thiévenaz, Nathan Vani, Alban Sauret
We investigate the link between the geometric environment of particles, the local deformations of the solvent, and the bulk effective viscosity in non-Brownian suspensions. First,…
