Numerical Analysis of Backward Inclined Impeller of Centrifugal Blower

A centrifugal blower is designed to handle compressible fluids like air and gases and is useful in ventilation, power stations, workshops etc. This paper focuses on numerical analysis of a backward centrifugal blower at different speeds of the impeller. A computational fluid dynamics model was developed in Ansys Fluent. The CFD simulation approach makes it possible to visualize the flow condition inside a centrifugal blower and solve for the required performance parameters. The k-ε turbulence method was modeled and solved using Ansys Fluent. Parameters like blower total pressure, flow rate, efficiency, and power were observed.
