Wet Steam Flowrate Calibration Facility
ASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 2, Fora, 2011Newly 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. Analysis

STEAM SEPARATING SOLVES PHASE SPLITTING PROBLEMS IN WET STEAM DISTRIBUTION SYSTEMS
Proceedings of CIM/SPE International Technical Meeting, 1990Abstract 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

The Size of the Steam Zone in Wet Combustion
Society of Petroleum Engineers Journal, 1975Abstract In the wet-combusion recovery process, the velocity of the heat front is normally greater than the velocity of the burning front because of the growth of a steam zone ahead of the burning front. This paper presents a method of calculating the size of this steam zone as a function of time.

The definition and measurement of wet steam properties
International Journal of Mechanical Sciences, 1969Abstract Possible states of thermal equilibrium and disequilibrium within a wet steam flow are examined. Proceeding from simplified models of the flow, a “general composite” property is proposed which is related to the respective mass concentrations, property magnitudes and velocities of the constituents.

Optical Measurement of Wet Steam in Turbines
Journal of Engineering for Gas Turbines and Power, 1998The wetness fraction of steam causes dangerous erosion of turbine blades and other components, and decreases efficiency of stages. The instrumentation of wet steam has, therefore, attracted growing interest from the point of safety and economical operation of power stations. Based on the light scattering technique, a method is presented that is capable

Property definition in equilibrium wet steam
International Journal of Mechanical Sciences, 1964Summary Equilibrium wet steam is a non-Newtonian fluid, and the meaning of the term “velocity” is obscure when a condition of slip is occuring. This paper explores the problems involved in framing a definition of velocity, and indicates the value of the concept of an equivalent filament, a device which also assists the definition of dryness fraction.

Critical Flow Properties of Wet Steam
Proceedings of SPE International Thermal Operations Symposium, 1993ABSTRACT Wet steam, being a two-phase fluid, has complex critical flow properties. Analytical and experimental data were used to investigate the critical steam flux, and the pressure ratio needed to achieve critical flow for a variety of popular flow-rate controlling devices.
