Abstract
The purpose of this work is to
study the influence of heat discharge rate and
effect of flow characteristics when modification
made on operating speed, blade thickness,
diameter of hub, vane angles, shape of blades.
This work is done on axial flow fan used in
automobiles. For this we use ANSYS software
for modeling of axial fan and by using
computational fluid dynamics, we compare the
results obtained by this analysis with the
existing.
