Abstract—As the diffusion of flow process is highly complex in centrifugal blower operation, it is necessary to design and develop the geometry of impeller and casing to reduce the flow losses significantly. In the present study, the methodology to find near optimum combination of blower operating variables for performance enhancement were analyzed using Computational Fluid Dynamics (CFD). Taguchi Orthogonal Array (OA) based Design of Experiments (DoE) technique to determine the required experimental trials. The experimental results are justified by Analysis of Variance (ANOVA) and confirmed by conformation experiments. The parameters chosen for design optimization are Impeller outlet diameter, Impeller wheel width, Thickness of blade, Blade width and Impeller inlet diameter. The levels for the parametric specification are chosen from the ranges and blade types where the blower will get the best efficiency. CFD results were validated by the fine conformity between the CFD results and the experimental results
