摘要

本文通过提取导流罩的轴向长度及叶顶间隙两个设计参数，构建了矩形流道内轴流风机的流场结构及仿真模型，进行了数值模拟和实验分析。结合仿真模型分析了矩形风道下轴流风机内部和出口流场特性的变化规律，构建了风机设计参数与气动性能之间的映射关系模型。通过风机气动性能实验可得：风机出口静压、体积流量和效率与间隙因子成反比，而与长度因子成正比，对比模拟值和实验值验证了模型的正确性。基于量化映射关系模型得到风机设计参数间隙因子和长度因子的最优值分别为0.8%和12.5%，为风机设计和冰箱风道优化提供量化参考。

Abstract

In this study

a flow structural model in a rectangular channel with an axial flow fan is established and analyzed through numerical simulation and experiments to get the influence of two design parameters

i.e.

axial length of the deflector and tip clearance

on the performance of axial flow fan. The mapping relationship between the design parameters and internal and outlet flow characteristics of the rectangular channel with an axial flow fan is also presented based on the simulation model. The experimental data revealed that the outlet static pressure

volume flow rate

and efficiency of the fan were inversely proportional to the clearance factor and directly proportional to the length factor. The comparison between the simulation results and experimental data validated the simulation model. Based on the mapping relationship

the optimal clearance factor and length factor of the fan design parameter factor were 0.8% and 12.5%

respectively

which could guide the design and optimization of a refrigerator duct structure.
