Abstract
In this study, mixing of non-Newtonian polymeric fluids was simulated three dimensionally using a power-law rheological model in a twin screw extruder. The simulation was performed by obtaining 3D components of velocity for each grid point using finite volume method and tracking the grid points in specified time intervals. To generalize the method to immiscible polymers, a modification was done by introducing interfacial tension and viscosity ratios of two fluids in solving velocity equations. The developed simulation method can be used to simulate the mixing of immiscible polymers.
