Abstract

The methods usually applied to the analysis of potential flow in the radial type hydraulic machinery, such as those by Busemann and Fujimoto, were exclusively conformal transformation of vane-profiles onto a unit-circle and representation of potential functions by expansion in series. Where as the present author, beginning with some consideration upon the construction of complex velocity function for "displacement flow" through the radial straight vanes in rotation, has found that it must be expressed in a strict form of some Abelian integral. Then he has succeeded in deducing a generalized integral expression applicable to any type of vanes which can be conformally represented to the former ones. This paper comprises all these fundamentals and also his theory of obliquely radial vanes and its numerical results.
