Analysis and Optimization of Centrifugal Blower Using CFD

Robert Paul. M

Centrifugal blowers play an important role in many industries. This project presents a design methodology to examine various parameters of the centrifugal blower using computational fluid dynamics approach and Finite Element Analysis concept. The effects of blower geometry, blower speed, impeller geometry, and blade design and fillet radius have been assessed. Total discharge and blower total efficiency are the output parameters calculated. The blower is modelled using Pro-E and after simplification the modelled blower is meshed in Gambit CFD. The solution is obtained using FLUENT. The post processing is carried out using ANSYS and the results are presented and discussed in detail. Based upon the ANSYS results once again blower parameters are changed and examined. Finally the optimum values of the parameters are obtained. These obtained values need to be implemented into the design for better performance of the blower.
