摘要
对4-72型离心通风机在不同流量系数的工况下进行三维数值模拟,通过比较、分析得出大流量与小流量之间的关系及增加出口扩压器的必要性。
The 3D numerical simulation on 4-72 type centrifugal fan is carried out under different flow coefficient conditions.The relationship between large flow and small flow is obtained by comparison and analysis.The results show that it is indispensable to add the outlet diffuser.
