基于Fluent的向心叶轮分析与优化

Analysis and Optimization of Centered Impeller Based on Fluent

文章建立叶轮及转鼓有限元模型,分析转鼓内流场变化。为满足大排量需求,对叶轮结构进行优化设计,建立了四种优化方案。通过整体流场分析,确定方案三为最佳方案,其转鼓排量由原先的64.2L/min提升至74.4L/min,提高了15.9%,解决了转鼓大排量的需求。

The finite element model of impeller and drum is established to analyze the change of flow field in drum. In order to meet the needs of large displacement and optimize the design of the impeller structure, four optimization schemes were established. Through the analysis of the whole flow field, the optimal scheme of the scheme 3 was determined. The drum displacement was increased from 64.2L/min to 74.4L/min, increased by 15.9%, to solve the large displacement of the drum needs.
