The models are implemented into an in-house computational fluid dynamics code that has been successfully applied to wet steam flow calculation for many years now. All models use the same condensation model that has been validated against the majority of available experimental data. The state equations for vapour and liquid water, the physical model as well as the numerical techniques of solution to flow governing equations have been presented. For the single-fluid model, the Reynolds-averaged Navier-Stokes equations for vapour/liquid mixture are solved, whereas the two-fluid model solves separate flow governing equations for the compressible, viscous and turbulent vapour phase and for the compressible and inviscid liquid phase. All described models have been compared with relation to the flow through the Laval nozzle.}, type={Artykuły / Articles}, title={Models for water steam condensing flows}, URL={http://www.czasopisma.pan.pl/Content/94303/PDF/03_paper.pdf}, doi={10.2478/v10173-012-0003-2}, keywords={Wet steam, Condensing flow models, Laval nozzle}, }
