| Abstract: | 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. |
