  1. Example:Polymer Extrusion

  2. Polymer extrusion Non-Newtonian flow, Carreau viscosity • Study the influence of shear rate dependent viscosity. • Linear polystyrene solution. • Carreau viscosity model .

  3. Polymer extrusion - Equations Equations • Momentum and continuity equations. • The viscosity is dependent on the shear rate • The Carreau-viscosity is given by

  4. Polymer extrusion - Geometry Geometry Due to rotational symmetry, we can reduce the model dimensions from 3D to axisymmetric 2D.

  5. Polymer extrusion - Results Velocity field • The average velocity is substantially lower at the outlet compared to the inlet, due to the rotational symmetry.

  6. Polymer extrusion - Results Non-Newtonian viscossity • Large variations in the contraction between the piston and the walls of the device. • The narrow channel generates large shear rates close to the walls.
