根据对贯流风机气动噪声的分析 ,研究了采用不等距叶轮的降噪机理。通过对等距与不等距叶轮的对比实验 ,验证了用不等距叶轮降噪的有效性
Based on the analysis of the aerodynamic noise of the cross flow fan, the noise reduction mechanism using the unequal impeller is studied. By comparing the isometric and non-equidistant impellers, the effectiveness of noise reduction with unequal impeller is verified
