Design Modification and Finite Element Analysis of Centrifugal Fan

Abstract

In this dissertation, the fluid flow and structural characteristics of centrifugal fan by changing the number of blades from 16 to 20 at different speeds and using different materials for blades are investigated. CFD investigation is performed on the fan to decide outlet velocities, pressures, mass flow rates & Reynolds number at different speeds 2800rpm, 3000rpm and 3200rpm. Static investigation is done by applying pressures obtained from results of CFD analysis as boundary condition. Distinctive materials Aluminum., E Glass Epoxy, Aramid Fiber are considered for the examination where displacements & stresses are established. 3D models of the centrifugal fan are done in Creo 2.0 and CFD & Static analysis are performed in Ansys 14.5.
