A Two-Dimensional Design Method for Highly-Loaded Blades in Turbomachines.

Abstract

This thesis presents a practical design method for highly-loaded blades in an isolated cascade. The flow is assumed to be incompressible and inviscid. The upstream inlet flow condition is taken to be uniform. The goals of this research are to provide a practical numerical code for the design problem, and a non-linear theory which can be easily expanded to three-dimensions. The theory is based in part on the Clebsh formulation. The blade profile is determined iteratively through the blade boundary conditions using a 'smoothing' technique. A practical numerical code is presented for the design problem using 'partial smoothing'. The program gives very fast convergence solutions with satisfactory accuracy for practical solidity range. Originator-supplied keywords include: Turbomachinery; Cascades; Inviscid flow; and Computational fluid dynamics.
