The sequence of typical models in turbomachinery: 1D, 2D and 3D is presented in the paper. For the one-dimensional model a diagram of energy losses is shown for the pump process. The 2D model is considered as axisymmetrical and the solution of inverse problem has been carried out. Model 3D The 3D model has been used to investigate some details of the flow pattern in rotor designed for a diagonal pump.

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.
