| Large stirred tank agitator strength calculation is difficult. and viscous fluid medium stirring power and stirring
effect is difficult to predict. For large fermentation tank agitator design problem. this paper adopted the method of
combining the CFD and FEA technology, mixing effect of fermentation tank and the agitator strength were analyzed and
predicted, the results showed that the analysis method considering the fluid pressure effect on the blade in the working
process. For large mixer, especially the mixing of medium intensity and power of agitator for viscous fluid prediction
could get more accurate results. the detailed flow field information and the feature parameters could be obtained at the
same time. This analysis method can provide reference for design and optimization of large mixer. |
