摘要
本文给出了空气气流轻叶片表面时,层流边界层所引起的空气动力噪的模型,并利用该模型,对某一型号的一类轴流通风机的层流边界层噪声进行了估算。
This paper gives the model of aerodynamic sound generated by the laminar boundary layer in axial flow fans. With this model, the paper gives the estimation and analysis of aerodynamic sound; generated by laminar boundary layer in one kind of axial flow fans.
