The finite element analysis and optimal design of aerator's blade

摘要

The inverted umbrella aerator is the key equipment of biological wastewater treatment technology,which have the effects of oxygenation,mixing and plug-flow.the design and optimization of the mixing impeller is most important to the efficiency of oxygenation.In this paper,a new aerator with curve blades was presented,and more,the working process of the blades have been studied through solid modeling,mesh generation and finite element analysis process,and the stress-strain finite element analysis was offered,which identified the weak links in the leaves and put forward the effective optimal measures.
