Abstract
In this paper, the effect of operational and geometrical parameters on the location of condensation onset and the rate of condensations are considered. These parameters are expansion rate of different geometry, inlet stagnation condition and the waves. To do so, a numerical method is presented to solve the two-dimensional two-phase steam flow over a series of geometries (such as nozzles, expansion corners and steam turbine blade-to-blade passages) by means of equilibrium thermodynamics model.
