The Oldroyd-B model has been used extensively to predict a host of instabilities in shearing
flows of viscoelastic fluids, often realized experimentally using polymer solutions. The …

The third edition of Bubbles, Drops, and Particles in Non-Newtonian Fluids provides
comprehensive coverage of the scientific foundations and the latest advances in particle …

Flow around a cylinder is a classical problem in fluid dynamics and also one of the
benchmarks for testing viscoelastic flows. The problem is of wide relevance to …

The sedimentation of a single particle in materials that exhibit simultaneously elastic,
viscous and plastic behavior is examined in an effort to explain phenomena that contradict …

A precision-machined cross-slot flow geometry with a shape that has been optimized by
numerical simulation of the fluid kinematics is fabricated and used to measure the …

We investigate purely elastic flow instabilities in the almost ideal planar stagnation point
elongational flow field generated by a microfluidic optimized-shape cross-slot extensional …

We employ time-resolved flow velocimetry and birefringence imaging methods to study the
flow of a well-characterized shear-banding wormlike micellar solution around a novel glass …

We examine the abrupt increase in the rise velocity of an isolated bubble in a viscoelastic
fluid occurring at a critical value of its volume, under creeping flow conditions. This 'velocity …

Part I of this paper [Haward et al., J. Rheol. 67, 995–1009 (2023)] presents a three-
dimensional microfluidic device (the optimized uniaxial and biaxial extensional rheometer …
