The presentation of CFX-TASCflow code possibilities for the turbomachinery design is the main aim of this study. In the first part of the work the compressor design process is presented. Next, CFX-TASCflow possibilities in predicting unstable operating conditions (surge) are shown. The one-stage, radial blower installed in the Institute of Turbomachinery TU of Lodz has been chosen owing to the available numerous experimental data. The pump calculations discussed in the third part concern a comparison of different turbulence models with the experimental results. In the last part devoted to the turbine design, the code usefulness is proved on the examples of the last stage design process.
