摘要
由于轴流式通风机小流量工况出现的非稳定工作特性,由此带来的缩小了风机的安全可靠运行区域,严重时可能带来颤振毁坏设备等安全性问题。通过数值模拟手段,对一矿用对旋式轴流式通风机小流量工况内部流动进行了深入研究。
Because of the unsteady properties of axial flow fan working under low flow rate condition the safe and reliable operation zone of the fan is reduced. And sometimes, serious vibration may bring about the unsafe factories or destroy the equipments. Therefore, it is necessary to solve the unsteady - stage conditions. By means of numerical simulation, the research on inner- flow of mining contra - rotating axial flaw fan working under low flow rate condition was made.
