Exit Flow Field and Performance of Axial Flow Fans
Journal of Fluids Engineering, 2005Flow fields near the exit and the global performance parameters of the various types of axial flow fans are studied with Particle Image Velocimetry and a standard AMCA 210 flow bench. The fans used in this study included the shrouded, shroudless, and winglet-blade types. The velocity vectors, streamlines, vorticity contours, velocity distributions, and

Laser Insight Into the Turbulent Swirl Flow Behind the Axial Flow Fan
Volume 1A: Aircraft Engine; Fans and Blowers, 2014Complex experimental study of the turbulent swirl flow behind the axial fan is reported in this paper. Axial fan with nine blades, designed to generate Rankine vortex, was positioned in the circular pipe entrance transparent section with profiled free bell mouth inlet. Two test rigs were built in order to study the turbulent swirl flow generated on the

Noise generation in axial flow fans
Journal of Sound and Vibration, 1966Abstract An empirical equation for fan noise is presented. The equation predicts, with fair accuracy, the noise of several fan configurations tested, yielding noise spectra over the frequency range 40 to 10,000 Hz at various fan speeds and over the measurable range of fan performance characteristics.
