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…
Uncertainty in Elastic Turbulence
Jack R. C. King, Robert J. Poole, Cláudio P. Fonte +1
Elastic turbulence can lead to to increased flow resistance, mixing and heat transfer. Its control -- either suppression or promotion -- has significant potential, and there is a c…
Large Amplitude Oscillatory Extension (LAOE) of dilute polymer solutions
Steffen M. Recktenwald, Thomas P. John, Amy Q. Shen +3
This study presents an experimental framework for large amplitude oscillatory extension (LAOE) to investigate nonlinear material properties of complex fluids. Using a microfluidic…
A new complex fluid flow phenomenon: Bubbles-on-a-String
Thomas P. John, Jack R. C. King, Steven J. Lind +1
A liquid jet plunging into a quiescent bath of the same liquid is a fundamental fluid mechanical problem underpinning a range of processes in industry and the natural world. Signif…
