Interplay of edge fracture and shear banding in complex fluids
Ewan J. Hemingway, Suzanne M. Fielding
We explore theoretically the interplay between shear banding and edge fracture in complex fluids, by performing a detailed simulation study within two constitutive models: the John…
Edge fracture instability in sheared complex fluids: onset criterion and possible mitigation strategy
Ewan J. Hemingway, Suzanne M. Fielding
We perform a detailed theoretical study of the edge fracture instability, which commonly destabilises the fluid-air interface during strong shear flows of entangled polymeric fluid…
Linear instability of shear thinning pressure driven channel flow
Hugh J. Barlow, Ewan J. Hemingway, Andrew Clarke +1
We study theoretically pressure driven planar channel flow of shear thinning viscoelastic fluids. Combining linear stability analysis and full nonlinear simulation, we study the in…
Edge-induced shear banding in entangled polymeric fluids
Ewan J. Hemingway, Suzanne M. Fielding
Despite decades of research, the question of whether solutions and melts of highly entangled polymers exhibit shear banding as their steady state response to a steadily imposed she…
Edge fracture in complex fluids
Ewan J. Hemingway, Halim Kusumaatmaja, Suzanne M. Fielding
We study theoretically the edge fracture instability in sheared complex fluids, by means of linear stability analysis and direct nonlinear simulations. We derive an exact analytica…
Thickening of viscoelastic flow in a model porous medium
E. J. Hemingway, A. Clarke, J. R. A. Pearson +1
We study numerically two-dimensional creeping viscoelastic flow past a biperiodic square array of cylinders within the Oldroyd B, FENE-CR and FENE-P constitutive models of dilute p…
Correlation lengths in hydrodynamic models of active nematics
E. J. Hemingway, P. Mishra, M. C. Marchetti +1
We examine the scaling with activity of the emergent length scales that control the nonequilibrium dynamics of an active nematic liquid crystal, using two popular hydrodynamic mode…
Viscoelastic and elastomeric active matter: Linear instability and nonlinear dynamics
E. J. Hemingway, M. E. Cates, S. M. Fielding
We consider a continuum model of active viscoelastic matter, whereby an active nematic liquid-crystal is coupled to a minimal model of polymer dynamics with a viscoelastic relaxati…
Moving contact line dynamics: from diffuse to sharp interfaces
Halim Kusumaatmaja, Ewan J. Hemingway, Suzanne M. Fielding
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…
Active Viscoelastic Matter: from Bacterial Drag Reduction to Turbulent Solids
E. J. Hemingway, A. Maitra, S. Banerjee +4
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 viola…
