Abstract
ABSTRACT
A numerical study is carried out to investigate the effect of
the addition of wing let to the end of blade on the axial fan
performance. Validation and assessment of the used computer
program FLUENT 6.2, is carried out by comparing its result
with previous researcher. Simulation is then carried out to
analyze the flow pattern with and without a winglet attached to
the fan blade. Velocity distribution produced numerically
showed that the winglet suppresses the secondary flow at the
tip gap. Pressure distributions also confirmed the winglet
advantages. Calculated performance of the fan used showed
general increase of the fan efficiency with 3.5% above those
without winglet at the optimum efficiency point and with up to
6 % at off design point.
