Instrumentation for wet steam

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004
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).

Wet Steam Flowrate Calibration Facility

ASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 2, Fora, 2011
Newly developed wet steam flowrate calibration facility is introduced. It has a closed loop in which boilers generate a steam flow up to 800 kg/h. Steam flow of known wetness up to 12% is generated by cooling down a dry steam flow by a heat exchanger. The wetness is calculated from the enthalpy the heat exchanger draws from the dry steam flow.

Wet-steam erosion of steam turbine disks and shafts

Power Technology and Engineering, 2011
A 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.

Effects of Wetness in Steam Turbines

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2005
Courses 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.

Wave propagation in wet steam

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004
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.

STEAM SEPARATING SOLVES PHASE SPLITTING PROBLEMS IN WET STEAM DISTRIBUTION SYSTEMS

Proceedings of CIM/SPE International Technical Meeting, 1990
Abstract Texaco operates several large steamflood projects in the Southern San Joaquin Valley in which individual wellhead mass flow rates and steam quality measurements are difficult to obtain. Uneven and unpredictable phase splitting at lateral and dead end tees is the problem (Hong, 1978,) In one instance, Texaco

Influence of Wet Steam on the Five-Stage Steam Turbine Efficiency

Volume 8: Microturbines, Turbochargers, and Small Turbomachines; Steam Turbines, 2018
In 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.

A metastable wet steam turbine stage model

Nuclear Engineering and Design, 2002
A model for the prediction of the efficiency of axial flow steam turbine stage is described, where the flow through turbine cascade is considered non-homogeneous and metastable. At the exit an oblique shock brings it to equilibrium. The losses in the cascade are expressed according to Dunham and Came (Trans. ASME (1970)) and Kacker and Okapuu (J.
