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 ...

Rotor wake characteristics of a transonic axial-flow fan [PDF]
AIAA Journal, 1985 State of the art turbomachinery flow analysis codes are not capable of predicting the viscous flow features within turbomachinery blade wakes. Until efficient 3D viscous flow analysis codes become a reality there is therefore a need for models which can describe the generation and transport of blade wakes and the mixing process within the wake.
