Abstract

Axial flow fans are
broadly applied in numerous industrial applications because of their
simplicity, compactness and moderately low cost, such us propulsion machines
and cooling systems. Computational fluid
dynamics techniques are commonly applied
to investigate flow phenomena through the axial fan and the rotor dynamic
performance. In the present work, a computational
model of an axial fan is presented in the current study. Numerical simulations
of a single stage axial fan on variable conditions have been performed to
obtain the detailed flow field of the centrifugal fan. The investigation of the current work is focused on the rotor–stator
configuration and the modeling of aerodynamic behavior of the blade rows. The
precise prediction of axial force and efficiency has essential implication for
the optimized operation of axial fan and the choice of thrust bearing.
Furthermore, it can act as guide for the geometrical and structural axial fan design
and the study of axial force prediction.
