NUMERICAL SIMULATION AND MODIFICATION OF 3D FLOW PHENOMENA IN AN AXIAL FLOW FAN
TASK Quarterly, 2003 This work aims to study and analyze the behavior of flow in an axial flow fan using numerical simulation based on solving Reynolds averaged Navier-Stokes equations coupled with a modified Spalart-Allaras turbulence model.

International Journal of Turbomachinery, Propulsion and PowerLarge-diameter axial-flow fans are predominantly used for cooling purposes, such as in air-cooled heat exchangers. Since it is difficult to experimentally test large-scale fans in the controlled environments provided by fan test facilities, smaller ...
