Theory of Centrifugal Type Impeller with Vanes of Arbitrary Form

抄録

This paper deals with the theory of the impeller of centrifugal type hydraulic machinery with vanes of arbitrary shape. The theory contains a method of conformal mapping based on a mapping function, which maps conformally an impeller with logarithmic spiral vanes. into a unit circle. The calculated results were compared with the experimental ones of impellers. with three types of vanes.
