阐述了主通风机产生噪声的类别,并就噪声的不良影响对通风机进行了结构流道优化设计,利用Fluent 6.0计算流体软件对风机的三维流场进行了模拟分析,同时进行了风机噪声的预估,同时对模拟结果进行了分析,模拟结果有助于了解风机内流场的运动规律,为进一步优化风机结构,降低风机噪声提供了有益的参考价值。
The types of noise produced by the main ventilator are expounded. The structural flow channel optimization design is carried out for the ventilator with the influence of noise. The three-dimensional flow field of the ventilator is simulated and analyzed by Fluent 6.0 computational fluid software. At the same time, the fan noise In the meantime, the simulation results are also analyzed. The results of the simulation are helpful to understand the law of the flow field in the fan and provide a useful reference value for further optimizing the fan structure and reducing the fan noise.
