The contribution deals with investigation of flow in the axial stage of the experimental turbine with reaction blading. The main intention is to evaluate an effect of the secondary flows on the efficiency. Most important source of the secondary flows is an outflow from the seal above the rotor shroud. Other sources of the secondary flows are axial gaps between the rotor disc and the side walls of the stator blade channel and the outlet diffuser. Results of the numerical simulation are compared with the experimental data. In this work there is also studied possibility of transfer the outlet dissipation structures at the inlet of the stage as an approach to modelling of the multistage configuration. |
