The dynamic properties of interfaces often play a crucial role in the macroscopic dynamics of
multiphase soft condensed matter systems. These properties affect the dynamics of …

The two main continuum frameworks used for modeling the dynamics of soft multiphase
systems are the Gibbs dividing surface model, and the diffuse interface model. In the former …

We report a study on the deformation and breakup of drops in an impulsively started shear
flow under Stokes flow conditions using boundary-integral simulations and video …

The extrusion of polymer melts is often rate limited by the onset of an elastic surface
instability known as sharkskin. Appearance of these surface distortions is generally …

We measure the flow kinetics of a polyethylene extruded through the exit of a sapphire
capillary tube in order to understand the nature of sharkskin, a surface roughness in the …

A comprehensive study of sharkskin behavior in linear polyethylene extrusion is carried out
to explore its molecular origin. Experimental characteristics are analyzed as a function of …

This paper reports experimental observations and numerical simulations relating to
sharkskin extrusion instabilities for two different types of polyethylene, a metallocene high …

The continually growing plastics market consists of more than 250 million tons of product
annually, making the recurring problem of polymer melt fracture an acute issue in the …

When certain critical conditions are exceeded, the flow of a polymer melt becomes unstable,
giving rise to particular phenomena that are the subject of this review. These instabilities are …

Flows of polymeric liquids undergo instabilities whose origins are quite different from those
of Newtonian flows, due to their elastic character and the complexity of the fluid/solid …
