TL;DR: In this paper, the authors present a description of two models dedicated to steam condensing flow modeling, which are implemented into an in-house computational fluid dynamics (CFD) code that has been successfully applied to a wet steam flow calculation for many years.

TL;DR: In this paper, a numerical method for modeling transonic steam flows with homogeneous and/or heterogeneous condensation has been presented, based on the time-dependent 3-D Reynolds averaged Navier-Stokes (RANS) equations coupled with two-equations turbulence model (k-ω SST) and additional conservation equations for the liquid phase.

TL;DR: In this article, experimental investigations of spontaneous condensation in transonic steam flow were carried out in nozzles and linear blade cascade for the tests of a small scale steam power station located at the Silesian University of Technology.

TL;DR: In this article, the computational results of the wet steam flow through the Laval nozzles for low and high inlet pressures were compared with experimental data, which constitutes validation tests of the condensation model implemented into an in-house CFD code solving the RANS equations for real gas equation of state.

TL;DR: The International Wet Steam Modeling Project (WSP) as mentioned in this paper reviewed the ability of computational methods to predict condensing steam flows, and the results of numerous wet-steam methods are comp...
