摘要
以矿用两级轴流式局部通风机为例,建立了通风机各部分的三维几何模型,通过非结构化网格划分将每个部分进行相应的划分,并对通风机气动噪声的产生原因进行原理上的分析,最后对通风机各部分进行气动噪声的声功率定性分析。
Taking the two-stage axial flow local ventilation fan for mining as an example, the three-dimensional geometric model of each part of the ventilation fan is established, each part is divided accordingly by unstructured meshing, and the causes of the pneumatic noise of the ventilation fan are analyzed in principle, and finally the sound power of each part of the ventilation fan is analyzed qualitatively for the pneumatic noise.
