摘　　要：由于风机的气动噪声在风机噪声中占有绝对优势,通过对矿用对选轴流风机的内部流场进行气动噪声数值模拟,对风机在一般工况和失速工况下的气动噪声进行了比较分析,并得出了相对的噪声值,为分析比较风机的气动噪声以及风机降噪提供了依据。Because fan＇s aerodynamic noise holds the overwhelming superiority in the air blower noise, by means of numerical simulation of aerodynamic noise, a comparative analysis of aerodynamic noise between normal condition and stall condition was carried to same relative annoyance value, the result can provide a basis for analysis and comparison of the aerodynamic noise and reduction the fan noise.
