A solution to inverse problem of quasi threedimensional flow in centrifugal impeller
Abstract
Account is taken of the fluid compressibility, the stream surface curvature, and the thickness variation of the stream surface in a solution calculated for the inverse problem of a quasithree dimensional flow past a centrifugal impellor. Equations for the rotation velocity, the irrotational condition for the absolute flow on the stream surface, the velocity potential, and the conjugate complex velocities in the stream surface are defined, with a density formulated for isentropic conditions. A singularity method is introduced in order to obtain solutions through numerical integration, and several numerical examples are provided. The model is demonstrated to show good agreement with measured values. Calculations using the model in consideration of the imposed velocity distribution are recommended in the design of the blade center line and the blade thickness.
