Numerical simulation of transonic flow of wet steam in nozzles and turbines

The paper presents several modifications of the flow model published in Stastny and Sejna (Proceedings of the 12th international conference of the properties of water and steam, Begel House, pp 711-719, 1995). Modifications related to the droplet growth model and the equation of state and their implementation into numerical code are described. The effect of droplet size spectra of incoming wet steam is also discussed. Numerical results of three-dimensional flow of wet steam in a turbine cascade show the effect of surface tension correction.
