内容記述 | An experimental investigation of a centrifugal fan was conducted with attention to the effects of the geometry of the casing on the aerodynamic and fan noise characteristics. A comparison of the fan noise and the aerodynamic characteristics of the tubular casing with those of scroll casing was made. As a result it was concluded that the aerodynamic characteristics of the fan with scroll casing were superior to those with tubular casing. The measured values of overall sound pressure level for both fans roughly same. When the ratio of inlet area to the outlet area of the impeller becomes nearly unity, the fan characteristics improve. For centrifugal fan with tubular casing, the rotating noise is generated by the interaction of impeller blades of the number with stator vanes and distorted inflow. | |||||
