A Computer Program for Calculating Potential Flow Solutions for Flow through Linear and Stationary. Circular Cascades.

Abstract

The Douglas Neumann Cascade Program has been rewritten so that it can analyze circular cascades with inward or outward radial flow directions, in addition to linear cascades for which it was originally developed. A solution for circular cascades is obtained by employing a conformal transformation which maps the circular cascade into a linear cascade. The capability available in the original program of analyzing multiple cascades has been preserved and can also be applied to circular cascades. In addition, the use of auxiliary storage has been modified and a new procedure for solving the system of equations for large problems has been developed which was found to significantly reduce the computation time. Included in this report is an explanation of the theory and a description of the program and its verification.
