Notes:
A simple extrusion process for Newtonian and power-law fluids is analysed. Marker particles are introduced to analyse the fluid flow motions. Area co-ordinates of six-node triangular element are used to determine the marker position in the element. With this element, the solution algorithm becomes simple compared with the one using the linear triangular element. The differences in flow and swell patterns between the two fluids are described.
