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.

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. Analysis

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

Optical Measurement of Wet Steam in Turbines

Journal of Engineering for Gas Turbines and Power, 1998
The 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

The Size of the Steam Zone in Wet Combustion

Society of Petroleum Engineers Journal, 1975
Abstract 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, 1969
Abstract 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.

Property definition in equilibrium wet steam

International Journal of Mechanical Sciences, 1964
Summary 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.

The three isentropic exponents of wet steam

Forschung im Ingenieurwesen, 1987
Real gas isentropic changes may be described using the three well known ideal gas relations,pv k =const, p(1−k)Tk=const andTv k-1=const, where exponent k has for each equation a different value kp, ν, kp, T and kT, ν respectively. In this paper the three isentropic exponents theory for real gases is extended to the two phase region.
