Vorticity Development in Highly Loaded Cascade Blades

Bagshaw, David; Ingram, Grant; Gregory-Smith, David; Atkins, W.S.

Abstract

A number of innovative techniques to reduce secondary flow, such as profiled endwalls and passage shaping have been proposed in recent years. This paper demonstrates how examining vorticity development through a highly loaded cascade can enhance the understanding of these complex technologies and their contribution to the design of modern machines. Such an understanding is necessary to fully exploit potential efficiency gains. The paper combines new experimental measurements with analysis of classical secondary flow theory for a turbine passage to build up a fuller picture of how innovative loss reduction techniques interact with secondary flows.
