In the paper numerical simulations have been performed to predict the performance of the diferent steam models. All of the considered models of steam condensation have been validated on the base of benchmark experiment employing expansion in nozzle and next on the low pressure part of the steam turbine equipped with the so-called Baumann stage. For numerical analysis three models have been finally used - the ideal steam model without condensation, an equilibrium steam model and an non-equilibrium steam model. It was confirmed that only the inclusion of the non-equilibrium effects in the computations can lead to a proper prediction of the condensation phenomena in the test nozzle. However the basic characteristics of the low-pressure part turbine can be succesfully estimated using simple ideal steam or the equilibrium condensation model.
