Investigation of Centrifugal Blower Noise

Noise Control and Acoustics, 1998
Abstract This paper presents the results of an investigation of centrifugal blower noise. Experiments on three different types of blowers were conducted to determine the major noise generation mechanisms. The information thus gained has led to an innovative noise reduction method utilizing a stationary, non-contacting transition mesh ...

Visualization of rotating vortex in a centrifugal blower impeller

Journal of Visualization, 2012
Rotating instability, RI, is a well-known unsteady phenomenon occurring in the off-design operation of various types of turbomachinery systems. However, the generation mechanism as well as its unsteady characteristics, especially in the case of centrifugal machines, has not yet been investigated in detail.
