Losses in transition segments between stages with different admission rates
Polanský J., Tajč L., Rudas B.
pages 266 - +9p., full text

Are given the results of the calculation study of the streaming in the stage with different admission rates and in the chamber between grades (stages) with different admission rates. The work is basically premised on the clarification of processes in the axial turbine 2 stage with partial steam admission. There is being investigated the influence of the axial wall, rapidity relationships and the Mach number on the efficiency of the stage. The simulation of the non-stationary steam flow through the stage and the transition canal was carried out by means of 'CFD' methods. Are being described the losses that emerge in the transition segment between stages with different 'partiality' Are being calculated pressure and velocity fields into the following stage. The knowledge of the problematic will enable to lower the losses to make better use of the energy and to lower the endangerment of the environment.
