基于FLUENT的多翼离心风机内部流场的数值模拟与参数优化

摘要

This paper simulates inner flow field of the centrifugal fan by using FLUENT, and the simulation re- sults simulation agree well with the experimental results acquired by MGS fan test data acquisition and the pro- cessing system. By analyzing the internal flow field, and by changing the volute width for research on the fan performance, the work lays foundation for optimizing the fan structure.%通过使用FLUENT软件对离心风机内部流场进行模拟，其结果与MGS通风机试验数据采集与处理系统试验所得结果吻合较好．分析风机内部流场情况，并通过改变蜗壳宽度对风机性能进行研究，为优化风机结构打下基础．
