Dynamic Simulation of 3D Fluid Field for Four-wing Synchronous Mixer Rotor And Four-wing Asynchronous Mixer Rotor

摘要

The physical, mathematical and finite element models for the four-wing synchronous rotors and four-wing asynchronous rotors in internal mixer were established in this paper. By comparative analysis of the two types of processes involved in mixing process the pressure field, the velocity field and the concentration field, the viscosity field and the mixed exponential distribution on its 3D fluid field dynamic simulation were computed by the polyflow software. The results showed that the four-wing synchronous rotors were better than the four-wing asynchronous rotors in a number of performance parameters.
