Two variants of a stage with modern 3D bladings were tested on a single-stage air turbine to determine the influence of relative width of stator blades (nozzles). The first case means a high-density nozzle row with t/Bax = 0.61; the second one represents a low-density row with t/Bax = 1.12. The 3D shaping of both nozzle cases is based on the same design features. Rotor blades (buckets) are kept the same (also 3D shaped). Comparisons of overall stage efficiency as well as measured flow fields data are presented in the paper.
