Centrifugal blower-dust collector

Chemical and Petroleum Engineering, 1987
The authors examine the working characteristics of the centrifugal blower-dust collector by means of aerodynamic tests made using clean air. The effect was also studied of the working regime and structural parameters of the blower-dust collector on the separation efficiency.

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.

Failure Analysis of a Large Centrifugal Blower

2019
Abstract A fracture mechanics based failure analysis and life prediction of a large centrifugal fan made from low-carbon, medium-strength steel was undertaken following shortcomings in attempts to explain its fatigue life from start stop cycles alone.

Low noise centrifugal blower

The Journal of the Acoustical Society of America, 1996
The present invention provides a centrifugal blower wherein the noise at the cutoff has been substantially reduced by providing a vortex in the air flow near the cutoff to redirect the air flow. A fin projects downwardly into the space created by the exhaust outlet to redirect the air flow away from the cutoff and create a vortex to quiet the air flow.

Design, Development and Analysis of Centrifugal Blower

Journal of The Institution of Engineers (India): Series C, 2017
Centrifugal blowers are widely used turbomachines equipment in all kinds of modern and domestic life. Manufacturing of blowers seldom follow an optimum design solution for individual blower. Although centrifugal blowers are developed as highly efficient machines, design is still based on various empirical and semi empirical rules proposed by fan ...
