Simulation of the Flow Field of Cement Mixer Based on Numerical Methods

摘要

Different kinds of research methods of the flow field in the cement mixer were introduced and compared, theory bases of the numerical simulation method of the flow field in the cement mixer were described, whole of thoughts of realization this method were analyzed. And then, the geometrical model and mathematical mode of the cement mixer were created by Fluent, which was based on CFD theory; and the characteristic of flow field in the cement mixer was simulated by Mixture model, SIMPLE algorithm and standard k-ε turbulence model. The calculation results showed that the distribution of flow field in cement mixer could be simulated preferably by the numerical technology, which supplied the valuable theoretical guidance for designing of the cement mixer.
