On sound generation mechanism by a centrifugal blower
The Journal of the Acoustical Society of America, 2002Centrifugal blower noise has often been modeled as dipoles and quadrupoles to account for the effects of fluid–structure interaction and turbulence as the impeller rotates. However, many experimental results have shown that sound powers from centrifugal blowers increase with speed to the power of 4–6, which implies the existence of a monopole ...

Centrifugal Blower with High Inlet Resistance
Journal of Fluid Machinery, 2003Comprehensive study on a centrifugal blower for air-purifier involving a few physical filters for percolation process has been accomplished for an optimal design of the air handling system. The filtering medi a causes a flow resistance for induced flows by a rotating impeller. The present methodology is to adopt PIV system for velocity measurements and

Housing effects on centrifugal blower noise
Journal of Sound and Vibration, 1974The sound power spectrum for a centrifugal blower operating at free delivery is characterized by enhancement at various frequencies owing to acoustical resonances in the blower housing. The lowest resonance frequency corresponds to the Helmholtz resonance and can be described by means of a lumped parameter analogy from which both the resonance ...

Inlet Guide Vane Performance of Centrifugal Blowers
Journal of Engineering for Power, 1961The function and effectiveness of the inlet guide vanes to control the blower output and power requirements are examined. Calculated and experimental results of the power reduction by means of guide vanes are presented. The concept of the “Inlet Specific Speed” widely used in centrifugal pump field is discussed in application to the blowers.
