Abstract:

The paper discusses the most general experimental results and compares the respective efficiencies of the various designs. After presenting the basic parameters of the stages under study, the report presents the influence of the relative width on total losses in various types of rotors, their degree of reaction during optimum operating conditions, the optimum entrance angle in vane-containing rotors as a function of channel diffusion properties, the behavior of vaneless diffusor stages, the maximum efficiency of the diffusors and working rotors as a function of the Reynolds number, the calculated efficiency of variously designed stages as a function of the relative width, and the calculated efficiency and the degree of pressure increase as a function of output.
