| Abstract: | In this paper,the flow field distribution and the issues occurred in static pressure measuring for A type air inlet chamber which conforms to GB/T 1236-2000 are studied when testing the characteristics of centrifugal fan and axial-flow fan within the small flowrate area.The test result shows that the static pressure has fluctuation on the measuring section of centrifugal fan and the distribution of static pressure along radial direction has differences in axial-flow fan.The factors affecting the distributio... |
