On numerical simulations of polymer extrusion instabilities
(2002)The objective of this study is mainly to review recent work concerning the numerical modeling of the stick-slip and gross melt fracture polymer extrusion instabilities. Three different mechanisms of instability are discussed: ...

The time-independent, compressible Poiseuille and extrudate-swell flows of a Carreau fluid with slip at the wall
(2003)We solve the time-dependent, compressible Poiseuille and extrudate-swell flows of a shear-thinning fluid that obeys the Carreau constitutive model, using finite elements in space and a fully-implicit scheme in time. Slip ...

A two-dimensional numerical study of the stick-slip extrusion instability
(2007)The time-dependent, compressible extrusion of a Carreau fluid is solved over the reservoir-die-extrudate region using finite elements in space and a fully implicit scheme in time. A nonmonotonic slip law based on experimental ...
