Sources of noise in axial flow fans

Journal of Sound and Vibration, 1964
Abstract The various possible mechanisms of noise generation in axial flow fans are described. Quantitative expressions have been derived for the sources of broad band noise by dimensional arguments, from which orders of magnitude estimates have been made.

Application of Numerical Design to an Axial Flow Fan

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">A numerical method was developed to establish a procedure for an axial flow fan design. Theory of free/force vortex motions, boundary element methods and optimization methods were applied to conduct this process. Rotational speed, ambient temperature and pressure were used as the input data; and tip diameter, hub ...

Optimized Design and Applications of Axial-flow Fan

2010 International Symposium on Intelligence Information Processing and Trusted Computing, 2010
Based on the design of axial-flow fans and Visual Basic6.0 and AutoCAD, the designing system of axial-flow fans has been designed and developed, which can function the aerodynamic calculation of blade cascade and auto drawing, and increased the modules of blade intensity checking, thus maximizing its safety.

An Investigation into the Performance of Axial Flow Refrigerator Fans

2014
This work was concerned with the aerodynamic and acoustic performance of small axial flow refrigerator fans. Relevant literature focusing on the principles of fan noise generation and fan system elements that contribute to noise generation was identified and discussed. A plenum chamber test rig was designed and constructed following ISO 10302-1.

Axial Flow Fan Design by Lattice Theory

1935
This thesis takes the much discussed and comparatively little used lattice theory and applies it to the design of fans. The application is made through the use of charts coming out of the theory. It is felt that by the use of the charts that the design of confined fans, that is those where end effects on the blades need not be considered, will be ...
