DYFP2006, the 13th int. conference on deformation, yield and fracture of polymers
Appl. Rheol. 16:5 (2006) 290-291
►
Since its start in 1970, the international conference
on Deformation, Yield and Fracture of Polymers
has been held every three years in Churchill
College, Cambridge, UK. Amongst the 'mechanical
properties of polymers' aficionados these
meetings have become known as the 'Churchill'
conferences, an event that has been established
as the leading conference on its subject world
wide. ...

Viscoelastic effects in multilayer polymer extrusion
Appl. Rheol. 16:4 (2006) 198-205
►
The effect of viscoelasticity on multilayer polymer extrusion is discussed. In these coextrusion processes predetermined
patterns are created with a remarkable breadth of complexity even in geometrically simple dies via
elastic rearrangements caused by the second-normal stress differences. A computational method is offered,
based on the mapping method, which quantitatively describes the flow-induced patterns. Besides that the
results are esthetically beautiful, they are also relevant for practice, since process and die design optimization
is now possible. Not only to minimize interface distortion, but potentially also to deliberately create new processes
and products based on this flow-induced patterning of polymers.

Chaotic mixing analyses by distribution matrices
Appl. Rheol. 10:3 (2000) 119-133
►
Distributive fluid mixing in laminar flows is studied using the concept of concentration distribution mapping matrices,
which is based on the original ideas of Spencer & Wiley [1], describing the evolution of the composition of two
fluids of identical viscosity with no interfacial tension. The flow domain is divided into cells, and large-scale variations
in composition are tracked by following the cell-average concentrations of one fluid using the mapping method of
Kruijt et al. [2]. An overview of recent results is presented here where prototype two- and three-dimensional timeperiodic
mixing flows are considered. Efficiency of different mixing protocols are compared and for a particular example
the (possible) influence of fluid rheology on mixing is studied. Moreover, an extension of the current method
including the microstructure of the mixture is illustrated. Although here the method is illustrated making use of these
simple flows, more practical, industrial mixers like twin screw extruders can be studied using the same approach.
