An experimental study of three-dimensional turbine blades combined with profiled endwalls.

Bagshaw, D.A. and Ingram, G.L. and Gregory-Smith, D.G. and Stokes, M.R. (2008) 'An experimental study of three-dimensional turbine blades combined with profiled endwalls.', Proceedings of the Institution of Mechanical Engineers, Part A : journal of power and energy., 222 (1). pp. 103-110.


This paper presents a detailed series of measurements on a novel design for reducing secondary flow in a linear cascade. The design of this geometry, which features profiled endwalls and three-dimensional blade shaping was discussed in a companion paper [1]. This paper presents the results of static pressure measurements on the blade surface, pneumatic pressure probe traverses, and surface oil flow visualization in order to build a comprehensive picture of the geometry's performance and function. Although the interactions between blade shaping and profiled endwalls are complex the experimental results show benefits over applying profiled endwalls alone.
