| Abstract: |
| The 2D finite element model of flow field in partially filled and fullfilled internal mixer at constant temperature by using the package FLUENT was investigated. By numerical simulating the free interface of compound， the flow state of fluid was analyzed， and the mixing efficiency of rotors was quantified in terms of shear stresses and mixing index generated in the flow field. The results showed that，compared with the full-filled internal mixer，the flow field became more complicated in partially filled internal mixer. The full-filled internal mixer seemed to provide better flow field characteristics for mixing， but the torque input to operate the machine was higher than that of the partiallv filled internal mixer. |
