Numerical Investigation of Mixing Properties of Continuous Mixer with New-type Rotors

摘要

In this paper, the 3D flow field and dynamic mixing processing in the continuous mixer with new-type rotors have been studied using finite element software package Polyflow. The influences of continuous mixer process conditions on mixing properties were analyzed by numerical simulation. The results show that the dispersion property is mainly affected by the rotational speed of rotors and the viscosity of polymer. Better dispersion property can be gained as and the viscosity increases. However, the distribution property is mainly affected by feed rate, and the distribution efficiency will reduce if feed rate is too fast.
