In this research a new finite element formulation for fluid flow computation will be presented which allows for computation of non-Newtonian polymer melts more efficiently than the previous work of D.H. Sebastian, et. al. A methodology for particle tracking in an Eulerian frame of reference will be presented which provides a distinct advantage over current Marker and Cell approaches to interface tracking in that his procedure also allows for computation of the cumulative strain history of the polymer melt in the mixers. The software tool defines complete particle trajectories in the mixing flute, quantifying distributive mixing, and detailing stress histories. The authors also present a control volume finite element formulation of the lubrication approximation of the flow equations which can be used to predict the pressure drop vs. flow rate information in cases where the complete fluid details are not necessary.
