The Prediction of Particle Concentration Distribution from a Slot Die

Abstract

Prediction of particle concentration distribution from a slot die is presented. The uniformity of particle concentration distribution is predicted by the particle trajectory in a slot die. In order to depict the movement of particles in the slot die, we coupled the one-dimensional flow equations in a slot die and Stokesian sedimentation equation. It is concluded that Reynolds number and particle diameters affect the uniformity of the particle concentration from the slit, and the predictions using the presented model agree with the experimental results.
