Abstract

This paper extends and generalizes the analytical technique outlined by Eck (1973), for determining the outer boundary curve of a volute symmetric about the plane of rotation of the impeller of a centrifugal fan, under conditions of ideal flow, based on the principle of conservation of mass. The general technique is demonstrated using a circular cross-section and the method is then extended to spiral volutes of novel geometric cross-sections including the ellipse, semi-ellipses and conjoined semi-ellipses. The resulting volutes are presented in graphical form, together with corresponding equations.
