Spreading dynamics of a drop of yield-stress fluid subject to vertical oscillations
Alice Woodbridge, Claudio P. Fonte, Anne Juel
The measurement of rheological properties from non-idealised flows is routinely used to characterise yield-stress materials. We extend the canonical slump test, which evaluates yie…
Yielded-region connectivity governs the onset of gravity-driven spreading in elastoviscoplastic drops
Alice Woodbridge, Patrick O'Rourke, Cláudio P. Fonte +1
The physical mechanisms controlling the onset of gravity-driven spreading of elastoviscoplastic drops remain unclear because yielding, elastic deformation, and viscous dissipation…
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…
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…
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…
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…
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…
Modern, Efficient, and Differentiable Transport Equation Models using JAX: Applications to Population Balance Equations
Mohammed Alsubeihi, Arthur Jessop, Ben Moseley +2
Population balance equation (PBE) models have potential to automate many engineering processes with far-reaching implications. In the pharmaceutical sector, crystallization model-b…
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…
Machine learning for viscoelastic constitutive model identification and parameterisation using Large Amplitude Oscillatory Shear
TP John, M Mowbray, A Alalwyat +4
Identification and parameterisation of constitutive models can be a challenging task in rheology. We investigate the use of Random Forest (RF) regression to estimate viscoelastic c…
A comparison between the FENE-P and sPTT constitutive models in Large Amplitude Oscillatory Shear (LAOS)
Thomas P John, Robert J Poole, Adam Kowalski +1
The FENE-P and sPTT viscoelastic models are widely used for modelling of complex fluids. Although they are derived from distinct micro-structural theories, these models can become…
