Abstract: [cze] [eng]
V práci bylo pomocí komerčního řešiče Fluent numericky vyřešeno proudění ve stupni VT3 turbíny 250 MW. Ve vyřešeném proudovém poli byly analyzovány vírové struktury a byla vypočtena reakce, účinnost a ztrátový součinitel celého stupně. The paper is concerned with numerical simulation of flow past the third high pressure stage of a 250 MW steam turbine. The flow field was solved using commercial code Fluent. Vortex structures were identified in the calcualted flow field and reactions, efficiency and loss coefficient of the whole stage were evaluated.
Keywords: numerical modeling; vortex identification; vortex structures
