Recent design of steam turbine stages is based on the use of 3D blades. This paper presents a comparison of experimental results from testing of three variants of this modern bladings with moderate hub reaction. The influence of row density of nozzles was investigated. Comparisons of overall stage efficiency as well as measured flow fields data are presented in the paper.
