摘要
对于KDF-5型对旋轴流风机进行研究,通过数值模拟和实验研究发现:在设计工况下,以轴流噪声为主;在小流量工况下,以涡流噪声为主。随着流量的减小,噪声变得越来越大。
KDF - 5 of axial flow fan is studied, numerical simulation and experimental research, the author found out that under the design conditions, give priority to with axial flow noise： in small flow condition, give priority to with eddy current noise. With the decrease of the flow, noise is becoming strong.
