Vibration and Noise of an Axial Flow Fan [PDF]
Periodica Polytechnica Mechanical Engineering, 2015 We describe a mechanical/acoustic study of a short-ducted axial flow fan. The purpose is to compare mechanical noise to that caused by flow phenomena. The eigenfrequencies of the fan are identified through measurement and finite element computations. The fan acoustics is evaluated by beamforming studies using the Phased Array Microphone technique.

Theory and Design of Axial Flow Fan (Part III)
Transactions of the Japan Society of Mechanical Engineers, 1953 The condition that the axial flow fan is to be operated at maximum efficiency is to make the overall manometric efficiency maximum taking also the loss of pipe line which is connected the fan into consideration. We show a disign to obtain the maximum manometric efficiency, in two cases where the diameter of impeller is determined freely or given, when ...
