It seemed very important to have a section on gas flow measurement. The UK's production of natural gas in 1984 was about 35×109 m3 and its consumption about 50×109 m3 with a reserve of about 0.7×1012 m3.* The value of this gas is 0.43 DM/m3† or about £0.12/m3 or about $0.18/m3. Unfortunately we were unable to find anyone able to write a section for this issue in the time available. However, I am grateful to Mr R J Simpson for drawing my attention to a report by Peignelin et al. † The authors have kindly agreed to an edited version of this paper. This paper considers two sizes of metering stations and considers the use of orifice or turbine meters. For these stations it considers investment costs and maintenance costs. It then examines the uncertainty in the energy content determination. The paper concludes that the major uncertainty lies in the flowmeter; that while turbine meter installations seem to be lower in cost than orifice meter installations, reliability must also be taken into account; and the cost of the instrumentation is a small proportion (15–20%) of the total cost of the station — R Baker.

Purpose – The purpose of this paper is to study a multiphase-flow instrumentation for film thickness measurement, especially impedance-based, not only for gas–liquid flow but also for mixtures of immiscible and more viscous substances such as oil and water. Conductance and capacitive planar sensors were compared to select the most suitable option for oil – water dispersed flow. Design/methodology/approach – A study of techniques for measurement of film thickness in oil – water pipe flow is presented. In the first part, some measurement techniques used for the investigation of multiphase flows are described, with their advantages and disadvantages. Next, examinations of conductive and capacitive techniques with planar sensors are presented. Findings – Film thickness measurement techniques for oil–water flow are scanty in the literature. Some techniques have been used in studies of annular flow (gas–liquid and liquid–liquid flows), but applications in other flow patterns were not encountered. The methods based on conductive or capacitive measurements and planar sensor are promising solutions for measuring time-averaged film thicknesses in oil–water flows. A capacitive system may be more appropriate for oil–water flows. Originality/value – This paper provides a review of film thickness measurements in pipes. There are many reviews on gas – liquid flow measurement but not many about liquid – liquid flow.

Flow velocity measurement was an important research of oil-gas-water three-phase flow parameter measurements. In order to satisfy the increasing demands for flow detection technology, the paper presented a gas-liquid phase flow velocity measurement method which was based on energy demodulation algorithm combing with time delay estimation technology. First, a gas-liquid phase separation method of oil-gas-water three-phase flow based on energy demodulation algorithm and blind signal separation technology was proposed. The separation of oil-gas-water three-phase signals which were sampled by conductance sensor performed well, so the gas-phase signal and the liquid-phase signal were obtained. Second, we used the time delay estimation technology to get the delay time of gas-phase signals and liquid-phase signals, respectively, and the gas-phase velocity and the liquid-phase velocity were derived. At last, the experiment was performed at oil-gas-water three-phase flow loop, and the results indicated that the measurement errors met the need of velocity measurement. So it provided a feasible method for gas-liquid phase velocity measurement of the oil-gas-water three-phase flow.

Summary Dedicated wet-gas flowmeters are now commercially available for the measurement of gas and liquid flow rates and offer a more compact measurement solution than does the traditional separator approach. The interpretation models of traditional multiphase flowmeters emphasize the liquid rate measurements and have been used to well test and meter mostly liquid-rich flow streams. These models were not developed for the measurement of gas flow rates, particularly those of wet gas. A new interpretation is described that allows a traditional multiphase flowmeter to operate in a dual mode either as a multiphase meter or as a wet-gas meter in 90 to 100% gas. The new interpretation model was developed for a commercially available multiphase flowmeter consisting of a venturi and a dual-energy composition meter. This combination results in excellent predictions of the gas flow rate; the liquid rate prediction is made with acceptable accuracy and no additional measurements. The wet gas and low-liquid-volume-fraction interpretation model is described together with the multiphase flowmeter. Examples of applying this model to data collected on flow loops are presented, with comparison to reference flow rates. The data from the Sintef and NEL flow loops show an error (including the reference meter error) in the gas flow rate, better than ± 2% reading (95% confidence interval), at line conditions; the absolute error (including the reference meter error) in the measured total liquid flow rate at line conditions was better than ± 2 m3/h (< ± 300 B/D: 95% confidence interval). This new interpretation model offers a significant advance in the metering of wet-gas multiphase flows and yields the possibility of high accuracies to meet the needs of gas-well testing and production allocation applications without the use of separators. Introduction There has been considerable focus in recent years on the development of new flow-measurement techniques for application to surface well testing and flow-measurement allocation in multiphase conditions without separating the phases. This has resulted in new technology from the industry for both gas and oil production. Today, there are wet-gas flowmeters, dedicated to the metering of wet-gas flows, and multiphase meters, for the metering of multiphase liquid flows. The common approach to wet-gas measurement relates gas and liquid flows to a "pseudo-gas flow rate" calculated from the standard single-phase equations. This addresses the need for gas measurement in the presence of liquids and can be applied to a limit of liquid flow [or gas volume fraction, (GVF)], though the accuracy of this approach decreases with decreasing GVF. The accurate determination of liquid rates by wet-gas meters is restricted in range. The application and performance of multiphase meters has been well documented through technical papers and industry forums, and after several years of development is maturing (Scheers 2004). Some multiphase measurement techniques can perform better, and the meters provide a more compact solution, than the traditional separation approach. It is not surprising that the use of multiphase flowmeters has grown significantly, the worldwide number doubling in little over a 2-year period (Mehdizadeh et al. 2002). Multiphase-flowmeter interpretation emphasizes the liquid rate measurement, and the application of multiphase flowmeters has been predominantly for liquid-rich flow stream allocation and well testing.

Anualmente, mais de 100 bilhões de metros cúbicos de gás são queimados mundialmente em flares nas instalações de petróleo e gás natural. Esse número era ainda maior a alguns anos atrás. No passado, o holofote estava sobre o petróleo e o gás natural era visto como uma fonte de energia não rentável. A preocupação mundial com o aquecimento global impulsionou as ações para redução das emissões de gases causadores do efeito estufa. A crescente mobilização dos órgãos reguladores de diversos países para imposição de restrições de queima e ventilação do gás natural vem contribuindo para a melhoria dos índices de aproveitamento do gás associado. Muito embora já tenha havido um avanço relevante, o montante de gás desperdiçado ainda precisa ser reduzido. Neste contexto, a necessidade de se quantificar corretamente os volumes desperdiçados de gás fica evidente. As ações para redução da queima ou ventilação de gás natural se baseiam fortemente em medições precisas. O reflexo disto são as constantes publicações de diretrizes regulatórias voltadas para as medições de vazão de gás dos sistemas de alívio/tocha. Apesar da medição de gás de flare não ser uma técnica nova, ela ainda é considerada desafiadora e bem diferente das demais aplicações de medição de vazão. A natureza imprevisível da queima de gás natural, associada a instalações inadequadas, torna a medição extremamente difícil e complexa. O presente trabalho traz uma visão geral da queima de gás natural, da regulação do tema no Brasil e no mundo e das características e desafios da medição de gás de flare. Adicionalmente, foram feitos estudos de incerteza sobre os volumes diários medidos nos pontos fiscais de gás de uma instalação típica, de forma a analisar a influência da incerteza da medição do gás de tocha sobre a incerteza da produção mensal de gás natural, que é a base de cálculo para as devidas participações governamentais. Também foram calculadas as diferenças obtidas entre a medição indireta (balanço volumétrico de gás) e a medição direta (medição ultrassônica) da queima de gás natural e as incertezas relacionadas à medição indireta.
Annually, more than 100 billion cubic meters of gas are flared from upstream oil and gas facilities. This number was even higher a few years ago. In the past, the spotlight was on oil and natural gas was seen as a non-profitable source of energy. The worldwide concern over global warming spurred actions to reduce emissions of greenhouses effect gases, contributing to change the scenario above. The increased mobilization of regulators from many countries enforcing gas flaring and venting restrictions has contributed to the improvement of gas use. However, although some progress has been already achieved, the amount of wasted gas still needs to be reduced. In this context, the need to correctly quantify the volumes of gas flared is evident. Actions to reduce the flaring or venting of natural gas rely heavily on accurate measurements. This reflects on the rigorous flare measurement guidelines introduced by many countries to support flaring legislation. Although the flare gas measurement is not a new technique, it is still considered a challenging task and quite unique compared to other flow measurement applications. The unpredictable nature of the flaring, many times happening at inadequate facility, makes measuring it extremely difficult and complex. This work provides an overview of gas flaring, regulatory requirements in Brazil and worldwide and the characteristics and challenges of flare gas measurement. In addition, uncertainty studies were made over the daily volumes measured in the fiscal points of a typical installation, in order to analyze the influence of the uncertainty of flared gas measurement on the uncertainty of monthly gas production, which is the basis for calculating the government takes. The differences obtained between the gas flaring indirect measurement (bydifference method) and direct measurement (ultrasonic measurement) were also calculated, as well as the uncertainties related to the indirect measurement.

The high pressure turbine stage can be considered the most important component for the efficiency and longevity of a modern gas turbine. The flow field within this stage is highly complex and is both unsteady and three-dimensional. Understanding this flow field is essential if improvements are to be made to future engine designs. Increasingly designers are placing more emphasis on the use of Computational Fluid Dynamics (CFD) rather than experimental results. CFD methods can be more flexible and cost effective. However before these predictions can be used they must be validated against experimental data at engine conditions. The hostile environment and complexity of flows within a gas turbine engine mean that collection of experimental data is extremely challenging. This thesis describes the development of an instrumentation technique for unsteady gas turbine flow measurement capable of resolving unsteady three-dimensional flow. The technique is based on an aerodynamic probe constructed with miniature semiconductor pressure transducers manufactured by Kulite Semiconductor Inc. Measurements recorded using this instrumentation technique from the Oxford Rotor experiment are presented to illustrate its use, and these in turn are compared with a CFD prediction of the rotor flow-field. This work was funded by the Engineering and Physical Sciences Research Council and Kulite Semiconductor Inc. The Oxford Rotor project is jointly funded by the Engineering and Physical Sciences Research Council (EPSRC), and Rolls-Royce Plc.

This thesis describes the development of a novel tomographic imaging system which can measure the concentration and velocity profiles in two-phase oil/gas flows. Two-phase flow measurement is a problem of great strategic and commercial importance to the oil industry. For example, an oilwell seldom produces just oil; there is often a significant quantity of gas and/or water present and it is very important to know how much of each is being produced. Unfortunately, this turns out to be a very demanding: task, particularly when the components have significantly different densities as in oil/gas flows. The fundamental problem with oil/gas flow measurement is that the individual components can arrange themselves in many different ways. This results in many possible concentration and velocity distributions, which in turn, render conventional flow measurement techniques inadequate. The tomographic system overcomes these problems by explicitly deriving the component distributions at two adjacent planes along a pipeline. These two images of the component distributions are then cross correlated on a pixel-by-pixel basis to obtain the velocity profile of the gaseous component. Multiplying the component concentration and velocity profiles yields a measure of the volumetric gas flow rate. The component distributions are obtained using two tomographic capacitance imaging systems. The problems caused by their interference have been examined in detail and this includes extensive electrostatic simulation studies. The field interactions are shown to affect the effective distance between the sensors and this varies with radial position, resulting in an effective separation profile". Numerous component distribution and velocity profile measurements are presented which were obtained from a 3" multi-phase flow loop, with superficial oil velocities ranging from 0.1m/s to 0.8m/s. and superficial gas velocities ranging from 0.05m/s to 0.5m/s. Void fractions range from 5% to 55%. The system is based on a combination of transputer and digital signal processor hardware and can reconstruct images at 180 frames per second. Techniques for real-time image correlation are examined and these, in combination with a number of suggestions for future work, will facilitate the development of a novel, real-time, multi-phase flow measurement system

Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. The flow conditions in chimneys of single family house boilers pose a challenge however, mainly because of the low flow velocity. The main objectives of the work were to characterize the flow conditions in residential chimneys, to evaluate the use of the Pitot-static method and the averaging Pitot method, and to develop and test a calibration method for averaging Pitot probes for low 𝑅𝑅𝑅𝑅.A literature survey and a theoretical study were performed to characterize the flow conditions in in single family house boiler chimneys. The flow velocities under normal boiler operating conditions are often below the requirements for the assumptions of non-viscous fluid justifying the use of the quadratic Bernoulli equation. A non-linear calibration coefficient is required to correct for these viscous effects in order to avoid significant measurement errors. The flow type in the studied conditions changes from laminar, across the transition regime, to fully turbulent flow, resulting in significant changes of the velocity profile during transient boiler operation. Due to geometrical settings occurring in practice measurements are often done in the hydrodynamic entrance region, where the velocity profiles are neither fully developed nor symmetrical. The predicted changes in velocity profiles are also confirmed experimentally in two chimneys.Several requirements set in ISO 10780 and ISO 3966 for Pitot-static probes are either met questionably or not met at all, meaning that the methods cannot be used as such. The main issues are the low flow velocity, viscous effects, and velocity profiles that change significantly during normal boiler operation. The Pitot-static probe can be calibrated for low 𝑅𝑅𝑅𝑅, but is not reliable because of the changing velocity profiles.The pressure averaging probe is a simple remedy to overcome the problems with asymmetric and changing velocity profiles, but still keeping low the irrecoverable pressure drop caused by the probe. However, commercial averaging probes are not calibrated for the characterized chimney conditions and the information available on the performance of averaging probes at low 𝑅𝑅𝑅𝑅 is scarce. A literature survey and a theoretical study were done to develop a method for calibrating pressure averaging probes for low 𝑅𝑅𝑒 flue gas flows in residential chimneys.The experimental part consists of constructing a calibration rig, testing the performance of differential pressure transducers, and testing a prototype pressure averaging probe. The results show good correlation over a wide operation range, but the low 𝑅𝑅𝑅𝑅 characteristics of the probe could not be identified due to instability in the chosen pressure transducer, and temperature correlation for one of the probes while not for the other. The differential pressures produced are close to the performance limitations of readily available transducers and it should be possible to improve the method by focusing on finding or building a suitable pressure transducer. The performance of the averaging method can be improved further by optimizing the geometry of the probe. Another way of reducing the uncertainty would be to increase the probe size relative to the conduit diameter to produce a higher differential pressure, at the expense of increasing the irrecoverable pressure drop.

Modeling of internal flow fields with hot, compressible fluids and sometimes combustion using cold flow techniques is discussed. The flow in a gas generator has been modeled using cold air. Experimental set up was designed and fabricated to simulate the unsteady flow with different configurations of inlet tubes. Tests were run for flow visualization and measurement of axial velocity at different frequencies ranging from 4 Hz to 12 Hz. Flow visualization showed that the incoming flow was a complex jet flow conformed to a cylindrical enclosure, while the outgoing flow resembled the venting of a pressurized vessel. The pictures show a complex flow pattern due to the angling of the jet towards the wall for the bent tube configurations and straightened flows with straight tube and other configurations with straighteners. Velocity measurements were made at an inlet Re of 8.1 x 10⁴ based on maximum velocity and inlet diameter using a single sensor hot wire anemometer at several locations in the plane of the inlet tube at 4 Hz, 8 Hz and 12 Hz for the straight tube and bent tube inlet configurations. The axial velocity near the entrance showed a strong component of the forcing frequency. Phase averaged mean velocities were observed to be well defined during charging and diminished during venting inside the cylinder. The jet flow penetrated most for the 4 Hz and least for the 12 Hz case. For the straight tube inlet comparison with a steady flow measurement of sudden expansion flow showed a qualitative similarity of the mean axial velocity distribution and centerline velocity decay during the charging phases. For the bent tube inlet case the contour plots showed the flow tendency towards the wall. Two cells were seen in the contours for the 8 Hz and 12 Hz cases. The deviation of the point of occurrence of maximum velocity in a radial profile was found to be about 6.5°. Entrance velocity profiles showed symmetry for the straight tube inlet while were skewed for the bent tube inlet. Contour plots of the phase averaged axial turbulence intensity for bent tube cases showed higher values in the core and near the wall in the region of impingement. Axial turbulence intensity measured for the straight tube case showed features as observed in an axisymmetric sudden expansion flow.

Annotation:

Measurements of flow velocity with cross correlation functions of ultrasonic signals show that the travelling time of structures deviates from the mean flow velocity. This difference usually is explained by the difference between the line integral of measurement and the area integral of the mean flow velocity. A comparison of the probability distribution of velocity components shows that the most frequent components in the fluid are in accordance with the travelling time of structures. The explanation is given by systems theory. In vortex shedding flow meters an ultrasonic wave is modulated by vortices behind a bluff body. The frequency of the vortices is proportional to the flow velocity. It depends on the size and arrangement of bluff bodies. As ultrasound is very sensitive to all kinds of modulating effects the size of bluff bodies can be drastically reduced in comparison to measurements with pressure sensors. Additionally the sensitivity can be increased, pressure losses behind the bluff body are considerably decreasing.

Annotation:

A practical system for flow measurement in rotating seals using the injection and sampling of a tracer gas is presented. Carbon dioxide or helium is injected as a tracer into a labyrinth seal at a controlled rate and gas samples are extracted downstream for concentration measurement. Test results from a rotating labyrinth seal rig were obtained over a range of seal pressure ratios and rotor speeds in order to determine the conditions which assure optimum tracer gas mixing. Seal leakage rates calculated by tracer gas concentration are compared to venturi flow measurements.

Annotation:

In this paper the newly built large scale low speed axial flow research compressor at Dresden University of Technology is presented. This compressor rig serves three main purposes. Firstly, it shall improve the understanding of compressor aerodynamics (especially secondary flows) by allowing detailed flow field measurements without heavily disturbing the flow. Secondly, it will be used to examine new design concepts. Thirdly, the detailed measurements in the absolute and relative system will be used for the calibration of existing CFD-codes. The design and the construction of the test rig which will allow an easy variation of the test configuration is described. A short view of the different data acquisition units for steady and unsteady measurement in the stationary and rotating system will be given. The blading of the compressor in the first series of test runs simulates a middle stage of a contemporary high-pressure compressor. Measurement data will be compared with results of 3D-Navier-Stokes calculations that were performed at MTU München.
