AB - The numerical investigation on the wet steam flow in the last two stages of a  1000 MW fossil-fired low pressure steam turbine is presented in this paper.  The non-equilibrium model via the classical nucleation theory is employed to  simulate the condensing flow of the wet steam. The characteristics of the  flow filed from design condition to low volume flow condition are calculated  and the static performance of last stage moving blade is also obtained. The  development of the backflow phenomenon is clearly captured through the  analysis of the velocity triangle.
