Abstract
The cause of pressure fluctuation occurred in a multi-stage centrifugal blower with inlet guide vane (IGV) under the partially opening condition of IGV was investigated using the system dynamics calculation based on the lumped parameter model. This pressure fluctuation occurred in the flowrate region where the slope of total static pressure-rise characteristic curve was steeply negative and total system seemed to be stable, hi our previous study, this pressure fluctuation was considered to be the mild surge that was caused by the stability balance between the first stage and the second to last stage. The system dynamics calculations could reproduce the mild surge behavior in the system and we confirmed that this pressure fluctuation was certainly the mild surge.
