Název v původním jazyce
A CFD study of an influence of the seal steam on the parameters of the two-stage experimental impulse steam turbine with the drum rotor arrangement
Popis výsledku v původním jazyce
The aim of the paper is to present the CFD analysis of the steam flow in the two-stage turbine with a drum rotor and balancing slots. The balancing slot is a part of every rotor blade and it can be used in the same way as balancing holes on the classical rotor disc. The main attention is focused on the explanation of the experimental knowledge about the impact of the slot covering and uncovering on the efficiency of the individual stages and the entire turbine. The pressure and temperature fields and the mass steam flows through the shaft seals, slots and blade cascades are calculated. The impact of the balancing slots opening or closing on the reaction and velocity conditions in the stages is evaluated according to the pressure and temperature fields. We have also concentrated on the analysis of the sealing steam flow through the balancing slots. The optimized design of the balancing slots has been suggested.
