Intelligent control of agitator can realize energy saving itself, and energy saving of agitator is also the driving force to realize intelligent control, and large-scale agitator provides favorable conditions for realizing intelligence and energy saving. Computational fluid dynamics (CFD) method is widely used in the simulation of flow field in stirred reactor, which provides a reliable way for the design and optimization of stirred reactor [20]. However, there are still many problems to be solved in the mixer, such as improving the prediction ability and simulation accuracy of CFD technology and solving the cleaning problem of micro mixer.
