Moving contact line dynamics: from diffuse to sharp interfaces (2015)
Journal Article
Kusumaatmaja, H., Hemingway, E., & Fielding, S. (2016). Moving contact line dynamics: from diffuse to sharp interfaces. Journal of Fluid Mechanics, 788, 209-227. https://doi.org/10.1017/jfm.2015.697

We reconcile two scaling laws that have been proposed in the literature for the slip length associated with a moving contact line in diffuse interface models, by demonstrating each to apply in a different regime of the ratio of the microscopic interf...

Clustering and phase behaviour of attractive active particles with hydrodynamics (2015)
Journal Article
Matas Navarro, R., & Fielding, S. M. (2015). Clustering and phase behaviour of attractive active particles with hydrodynamics. Soft Matter, 11(38), 7525-7546. https://doi.org/10.1039/c5sm01061f

We simulate clustering, phase separation and hexatic ordering in a monolayered suspension of active squirming disks subject to an attractive Lennard-Jones-like pairwise interaction potential, taking hydrodynamic interactions between the particles ful...

Age-Dependent Modes of Extensional Necking Instability in Soft Glassy Materials (2015)
Journal Article
Hoyle, D. M., & Fielding, S. M. (2015). Age-Dependent Modes of Extensional Necking Instability in Soft Glassy Materials. Physical Review Letters, 114(15), Article 158301. https://doi.org/10.1103/physrevlett.114.158301

We study the instability to necking of an initially cylindrical filament of soft glassy material subject to extensional stretching. By numerical simulation of the soft glassy rheology model and a simplified fluidity model, and by analytical predictio...

Active Viscoelastic Matter: From Bacterial Drag Reduction to Turbulent Solids (2015)
Journal Article
Hemingway, E., Maitra, A., Banerjee, S., Marchetti, M., Ramaswamy, S., Fielding, S., & Cates, M. (2015). Active Viscoelastic Matter: From Bacterial Drag Reduction to Turbulent Solids. Physical Review Letters, 114(9), Article 098302. https://doi.org/10.1103/physrevlett.114.098302

A paradigm for internally driven matter is the active nematic liquid crystal, whereby the equations of a conventional nematic are supplemented by a minimal active stress that violates time-reversal symmetry. In practice, active fluids may have not on... Read More about Active Viscoelastic Matter: From Bacterial Drag Reduction to Turbulent Solids.
