Abstract

Centrifugal fan impellers with aerofoil blades are analysed using the concept of cyclic symmetry. Impellers with single cover plate alone are considered. Both static and dynamic analyses are done and user‐friendly programs for the design of these impellers are developed. In addition, parametric studies were also undertaken. Variations of maximum stress and the lowest frequency with the various values of both the outer diameter and thickness of the impeller plates was carried out, and the results plotted.
