Optimization of Primary Air Fan Impeller using Ansys

An effort has been made for optimizing the design of constant thickness forward curved bladed radial fan impeller into aerofoil shape forward curved bladed radial fan impeller by finite element analysis (FEA) for material cost and weight reduction for power savings. The design is done by mechanical software named ‘ANSYS'. To achieve this, the thickness of every component of the impeller was reduced and constant thickness blades were replaced by aerofoil shape blades. Stress and deflection were analyzed for the modified and existing design within the limit and the final result showed a 14% weight reduction in the net weight of the impeller. Hence this project helped in the following ways: •Net weight reduction by 14%. •Material cost reduction. •Power savings. •Minimizing the vibration level.• Lower noise generation Citation: D.
