Evaluation of cup-type jig for parallel plate rheometer by viscoelastic flow simulation
In order to measure the flow characteristics of polymer melt with high melt index, e.g. polyester and polyethylene terephtalate (PET) used for fiber processing, we discuss the utility of the cup-type jig for measurement of the steady-state shear flow ...

VISCOELASTIC FLUID FLOW FEATURES IN THE DISK-SHAPED GAP EXTRUDER
Disk-shaped gap extruders have higher plasticizing and homogenizing power than screw extruders, but the forming pressure which they develop is lower. Therefore, they are mainly used as mixers or granulators for loading the prep- aration material into ...

Biological benefits of collective swimming of sperm in a viscoelastic fluid
Collective swimming is evident in the sperm of several mammalian species. In bull (Bos taurus) sperm, high viscoelasticity of the surrounding fluid induces the sperm to form dynamic clusters.

A Blowup Criterion for Ideal Viscoelastic Flow [PDF]
We establish an analog of the Beale-Kato-Majda criterion for singularities of smooth solutions of the system of PDE arising in the Oldroyd model for ideal viscoelastic flow.
