摘要
以某型号空调室外机轴流风机为研究对象,利用ANSYS Fluent软件,预估了风机表面气动噪声源的分布并预测了远场接收点位置噪声特性。用数值计算的方法预测空调风机的气动噪声为空调风机的降噪设计提供参考。对空调系统中其他部件的声源识别和频谱特性分析也具有一定的借鉴意义。
By applying an air conditioner outdoor fan as an example,the ANSYS Fluent software is used to estimate the distribution of aerodynamic noise sources on the surface of the fan and to predict the noise characteristics of the far-field receiving point. It is useful to use the numerical method to predict the aerodynamic noise of the air conditioning fan to provide reference for the noise reduction design of the air condition fan.It also has some reference for the sound source identification and spectrum characteristic analysis of other components in the air conditioning system.
