摘要

对某高效低噪音离心风机的集流器进行了优化设计研究

首先通过数值计算得到了在初始设计的集流器扩张角、集流器收缩角和扩张段长度等参数下的离心风机气动性能

并与实验结果进行对比验证

在此基础上采用响应面方法进行二次回归拟合

得到了锥弧型集流器扩张角、收缩角和扩张段长度与风机效率及声功率级之间的函数关系并进行了优化分析

由此得到使风机性能最优的集流器参数。分析结果表明

锥弧型集流器对离心风机气动性能的影响比较显著

对声功率级的影响不太显著

锥弧型集流器的扩张角、收缩角对离心风机气动性能的影响明显

而集流器扩张段长度对气动性能的影响很小。优化后的集流器使得离心风机的效率提升了3.6%

静压提高了4.1%

声功率级降低了1.7 dB。

Abstract

Optimization design method for the inlet collector of a centrifugal fan with high-efficiency and low-noise is investigated. The aerodynamic performances of the centrifugal fan are obtained by numerical simulation in the original parametric design

including the divergence angle and shrinking angle of the fan inlet collector

and the length of the divergent section. The numerical calculation is compared with the experimental result to validate the accuracy of the algorithm. To improve the aerodynamic and acoustic performances of the centrifugal fan

quadratic polynomial regression is considered to analyze the function relation of the centrifugal fan performance and the fan inlet collector parameters

and the optimal structure parameters of centrifugal fan inlet collector are obtained. The results indicate that the three fan inlet collector parameters exert remarkable effects on the aerodynamic performances

but slight effect on sound power level. The divergence angle and shrinking angle of the fan inlet collector obviously affect the aerodynamic performances

while divergent section length does not. After optimizing the centrifugal fan inlet collector

the efficiency and static pressure ratio increase by 3.6% and 4.1%

respectively

and the sound power level decreases by 1.7 dB.
