Abstract
In the low-pressure part of steam turbine, the state path usually crosses the saturation line in penultimate stages. At least last two stages of this part of turbines operate in two –phase region. The liquid phase in this region in mainly created in the process of homogeneous and heterogeneous condensation. Several observations confirm however, that condensation often occurs earlier than it is predicted by theory i.e. before the Wilson line. It is because the nucleation can start at some soluble and insoluble impurities, particle of dust, chemical compounds or corrosion products. In the present paper we have focused on the prediction of the spontaneous condensation in wet steam flow. Two main types of non-equilibrium condensation models are considered and compared. These are: the single continuum approach and eulerian-eulerian multi-phase approach.
