Simulation of the Mixing in a Novel Fully Wiped Co-Rotating Non-Twin Screws

Article Preview

Abstract:

This work aims at simulation of the mixing performance in the novel co-rotating non-twin screw group developed by the authors. The simulation concerns the incompressible fluid obeying Carreau flow model. Using the mesh superposition technique, the mixing performance in such novel mixing sections, as well as in the conventional twin screw groups with one and two tips, are simulated. Adopting the particle tracking technique, distributive mixing is visualized by the evolution of the mixing of a cluster of particles in addition to using the segregation scale. Dispersive mixing is evaluated using mixing index in combination with the probability distributions of cumulative mixing index. The computational results reveal that the novel screw group is superior in mixing ability.
