Results of the International Wet Steam Modeling Project
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2018 The purpose of the “International Wet Steam Modeling Project” is to review the ability of computational methods to predict condensing steam flows. The results of numerous wet-steam methods are compared with each other and with experimental data for ...

Analysis and design of wet-steam stages
, 2017 In most conventional power plants the turbines are supplied with superheated steam but, during the course of its expansion, the condition of the steam enters the two-phase region and the last few low-pressure (LP) stages operate in the wet steam regime ...

This paper is devoted to the measuring methods and instrumentation used in the wet-steam area for both aerodynamics measurements (pressure, temperature and velocity) taking into account the interaction between the vapour and the liquid phase, and the characterization of the liquid phase itself (dispersed phase and liquid film).

Effects of Wetness in Steam Turbines
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2005Courses in mechanical engineering usually introduce the theory of axial-flow turbo-machines in terms of simple velocity triangles representing the bulk flow of ideal compressible fluid through the blade passages. A distinctive practical difference, peculiar to steam turbines (ST), is the presence of liquid-water in the flow field. The

Wet-steam erosion of steam turbine disks and shafts
Power Technology and Engineering, 2011A study of wet-steam erosion of the disks and the rotor bosses or housings of turbines in thermal and nuclear power plants shows that the rate of wear does not depend on the diagrammed degree of moisture, but is determined by moisture condensing on the surfaces of the diaphragms and steam inlet components.

Abstract A wet steam tunnel was constructed to simulate the ineteraction of liquid and vapour in order to investigate the nature and origin of static electrification phenomena which occur within wet steam turbines. The tunnel was operated at 0·17 bar pressure with steam velocity up to 290 m/s.

Influence of Wet Steam on the Five-Stage Steam Turbine Efficiency
Volume 8: Microturbines, Turbochargers, and Small Turbomachines; Steam Turbines, 2018In the paper the behaviour of the five-stage experimental steam turbine 10 MW is described during the expansion transition from superheated steam to wet steam as well as the influence of wet steam on the flow path efficiency. The influence of wet steam occurrence on one to four last stages is given by setting the inlet steam parameters.

Linear wave equations for equilibrium and subcooled wet steam are introduced in the paper, accounting for thermal and inertial relaxation processes between the vapour and droplets. Relations for sonic velocity and absorption were found to be frequency dependent.
