Abstract

The paper presents the results of viscous flow modeling using different turbulence models in the Ansys CFX program
for the D. Eckardt and H. Krain stage. The impellers are with an outlet angle of 90 and 60 degrees. Isentropic
efficiency and the total pressure ratio are compared with the experimental data. The evaluation of the static pressure
contours structure at the impeller shroud is made. Recommendations for qualitative modelingof high-head stages
are given.
