Light-scattering reconstruction of transparent shapes using neural networks
Tymoteusz Miara, Draga Pihler-PuzoviÄ, Matthias Heil +1
The accurate characterisation of the 3D deformations of slender fibres and thin sheets in flow, is a key experimental challenge in the study of particle-laden flows. We propose a h…
Network modelling of yield-stress fluid flow in randomly disordered porous media
Cláudio P. Fonte, Elliott Sutton, Kohei Ohie +3
Yield-stress fluid flow through porous media is governed by a strong coupling between rheology and pore-scale geometry, leading to nonlinear, non-Darcy transport and pronounced cha…
Sub-Yield Dynamics in Yield-Stress Materials
Alice Woodbridge, Kasra Amini, Fredrik Lundell +4
The mechanical response of yield-stress materials below the yield point remains a subject of debate. Two of the most widely used constitutive models for these materials offer funda…
Predicting the distribution of yield-stress fluids in branched pipe manifolds
Elliott Sutton, Waldo Rosales Trujillo, Adam Kowalski +2
We develop a one-dimensional network model to predict the steady-state distribution of yield-stress fluids in branched pipe manifolds under wall-slip conditions. The model accounts…
Dynamics of evaporating, interconnected droplets
Chenyang Ren, Sri Ganesh Subramanian, Shresht Jain +3
We report on the dynamics of a pair of sessile droplets that are connected by a microchannel, yet open to the atmosphere and hence free to evaporate. Our results reveal that fluid…
On the oscillatory dynamics of a Saffman--Taylor finger with a bubble at its tip
Jack Lawless, Andrew L. Hazel, Anne Juel
The complex behaviour of air-liquid interfaces driven into Hele-Shaw channels at high speeds could arise from oscillatory dynamics; yet, both the physical and dynamical mechanisms…
