Extrusion of power-law shear-thinning fluids with small exponent

Abstract:

The slow flow of power-law shear-thinning fluids during extrusion is considered for materials where the exponent is asymptotically close to zero. Such flows arise in a number of practical industrial problems and give rise to some unexpected effects. Three different regions of extrusion flow are examined. First, some simple results for unidirectional flow in a one-dimensional channel are considered. Secondly, the region near to the die exit is then considered, and it is noted that an exponenti...
