Abstract
The flow of a quasi Newtonian model fluid, which allows shear thinning as well as extension thickening, through a sudden planar 4:1 contract ion is studied numerically. Comparing with numerical results for a pur ely shear thinning fluid differences show up which follow the trend of experimental data.
