▪ Abstract Filament-stretching rheometers are devices for measuring the extensional
viscosity of moderately viscous non-Newtonian fluids such as polymer solutions. In these …

A microneedle is a three-dimensional (3D) micromechanical structure and has been in the
spotlight recently as a drug delivery system (DDS). Because a microneedle delivers the …

We study the elasto-capillary self-thinning and ultimate breakup of three polystyrene-based
ideal elastic fluids by measuring the evolution in the filament diameter as slender …

We investigate the nonlinear shear and uniaxial extensional rheology of entangled
polystyrene (PS) melts and solutions having the same number Z of entanglements, hence …

We investigate the steady and transient shear and extensional rheological properties of a
series of model hydrophobically modified ethoxylate− urethane (HEUR) polymers with …

A new filament stretching rheometer has been constructed to measure the elongational
viscosity of polymer melts at high temperatures. Two polymer melts, a LDPE and a LLDPE …

The smoothed particle hydrodynamics (SPH) method is extended and tested for the
numerical simulation of transient viscoelastic free surface flows. The basic equations …

This work is concerned with the development of a numerical method capable of simulating
viscoelastic free surface flow of an Oldroyd-B fluid. The basic equations governing the flow …

Following development of a filament-stretching extensional rheometer at Monash University,
similar rheometers have been designed and built in other laboratories. To help validate the …

The large extensional viscosity of dilute polymer solutions has been shown to dramatically
delay the breakup of jets into drops. For low shear viscosity solutions, the jet breakup is …
