In the last time numerical modeling method of aerodynamic processes gains spreading. This emergence is caused by rapid development of computer facilities and progress in development of numerical methods for the solution of aerodynamic tasks. In the present work numerical methods were used. The choice of this subject is caused by that attention which is paid to experimental data about non-uniformity of flow parameters in flowing part of the turbine. It is considered that the non-uniform distribution of flow parameters by radius leads to decrease of stage efficiency. However, experimental data on this matter are absent. This work is attempt to fill this shortcoming.
