Abstract

An attempt has been made to predict flow behavior of the rub bery material in an internal mixer by means of finite element analysis. For the convenience of analysis, a simplified model for the mixer and some assumptions were introduced. The model consists of a circular cylinder and a rotor with uniform cross sectional shape along the axis which rotates around the axis located at the center of the cylinder. Rubbery material fills the void between the cylinder and the rotor. The assumptions are: the material is a power law liquid, the material is incompressible, and the viscosity is large enough to allow laminar flow.
