THE EFFECT OF IMPELLER BLADE DESIGN ON CENTRIFUGAL BLOWER – CFD APPROACH

Golla Jyothi, A. Vinutha

Abstract


A centrifugal blower is a mechanical device for moving air or other gases with a slight increase in pressure. While working with hot air, the heat absorbed by the impeller material should be dissipated effectively to avoid the accumulation of heat at one place, that may deform the part. The rate of dissipation depends on the heat transfer rate and the thickness of the blade material. The present work deals with the determination and analysis of heat transfer rate of blade made of Aluminum alloy, composite materials Graphite and Carbon Fiber with blade thickness 1mm, 2mm, 3mm. This is done using ANSYS software in thermal analysis. CREO parametric software is used for modeling the centrifugal blower. The performance of Blower depends on the change in static pressure for different input velocities of air. In CFD analysis change in pressure, outlet velocity, heat transfer coefficient of air is determined at different input velocities 14m/sec, 16m/sec, 18m/sec, 20m/sec and 22m/s.
