Similarity Theory Design of Centrifugal Fan’s Impeller
At present a set of wholly mature design methods of impeller theory based on existential experiences do not exist, because of the complexity of internal flow characteristics of centrifugal fan. Therfore it will undoubtedly provide helps for the improving of existing mehtods to fully master the existed successful experience. Based on statistical datas, some new methods used to determine the main geometric parameters of centrifugal fan’s impeller was proposed in this paper.The paper analyzes the internal relations between a large number of existing aerodynamic sketches and performance parameters of centrifugal fans by means of statistical method and finds regularity, so provides help for simplifing calculation procedures and improving the reliability of impeller design.
