Abstract:
Background Accurately and unobtrusively testing the effects of snoring and sleep interventions at home has become possible with recent advances in digital measurement technologies. Objective The aim of this study was to examine the effectiveness of using an adjustable bed base to sleep with the upper body in an inclined position to reduce snoring and improve sleep, measured at home using commercially available trackers. Methods Self-reported snorers (N=25) monitored their snoring and sleep nightly and completed questionnaires daily for 8 weeks. They slept flat for the first 4 weeks, then used an adjustable bed base to sleep with the upper body at a 12-degree incline for the next 4 weeks. Results Over 1000 nights of data were analyzed. Objective snoring data showed a 7% relative reduction in snoring duration (P=.001) in the inclined position. Objective sleep data showed 4% fewer awakenings (P=.04) and a 5% increase in the proportion of time spent in deep sleep (P=.02) in the inclined position. Consistent with these objective findings, snoring and sleep measured by self-report improved. Conclusions New measurement technologies allow intervention studies to be conducted in the comfort of research participants’ own bedrooms. This study showed that sleeping at an incline has potential as a nonobtrusive means of reducing snoring and improving sleep in a nonclinical snoring population.

Abstract:
We extend a recent theory for steady uniform gravity-driven flow of a highly concentrated granular-fluid mixture over an erodible bed between frictional sidewalls. We first include angles of inclination greater than the angle of repose of the particles; then, we introduce a boundary condition for flow over a rigid bumpy bed. We compare the predictions of the resulting theory with the volume flow rates, depths and angles of inclination measured in the experiments on dry and variously saturated flows over rigid and erodible boundaries. Finally, we employ the resulting theory, with the assumption that the flow is shallow, to solve, in an approximate way, for the variation of height and average velocities along a steady non-uniform inclined flow of a granular-fluid mixture that moves over a rigid bumpy bed. The solutions exhibit features of the flow seen in the experiments – for example, a dry bulbous snout in advance of the fluid, whose length increases with increasing number of the particles and that disappears with increasing velocity – for which satisfactory explanations were lacking.

Abstract:
Background: Highly-inclined and horizontal wells have been widely used for the development of mature oilfield, marine oilfield, and low permeable oilfield. During drilling operations, cutting particles will accumulate in the low side of wellbore and cuttings bed may be formed, which may lead to high drag and torque, stuck pipe, and other drilling problems. We reviewed the patents about cutting bed cleaning tool. Objective: The goal of this work is to determine the incipient motion velocity or rate to re-suspend and remove the cutting particles. Methods: In this study, the random distribution function of particles is introduced to determine the percentage of incipient particle motion, and the mechanical models for rolling and lifting method considering the net gravity, drag force, lift force, additional mass force, adhesive force and flow pressure gradient force are developed to predict the incipient motion velocity or rate. Also, the model has been verified by published experimental data. Results: The critical particle size of incipient motion rate is approximately 1 mm. The incipient motion rate decreases as the height of cuttings bed decreases, and the minimum flow rate that prevents the bed formation may be estimated when bed height is small enough. Also, increasing wellbore inclination or fluid density has a positive effect on incipient motion rate, but increasing particle density or percentage of incipient particle motion has an adverse effect. Conclusion: This study may provide a guideline for designing hydraulic parameters and sand washing in the highly-inclined and horizontal wells, thereby contributingin economic production.

Abstract:
The transport of proppant-fracturing fluid mixture in a fracturing pipe can significantly affect the final proppant placement in a hydraulic fracture in horizontal well fracturing. To improve the understanding of the hydrodynamic performance of proppants in a curving fracturing pipe, a modified two-layer transport model was proposed by taking the viscoelastic properties of carrier fluid into consideration. Fluid temperature was determined by an energy equation in order to accurately characterize its rheological properties, and the Chang–Darby model was used to represent the viscosity-shear rate relationship. The flow pattern of particle-fluid mixture in a curving fracturing pipe was investigated, the effects of particle and fluid properties and injection parameters were analyzed, and a flow pattern map was established. Three transport stages are observed: (1) particles keep suspended in the carrier fluid at small inclined angle; (2) a small number of particles settle and accumulate on pipe bottom to form a particle bed load flow at intermediate inclined angle; (3) numerous particles settle out of carrier fluid and the particle bed quickly develops in an approximate horizontal pipe. The transition processes between different stages were observed, and the transition velocity from particle bed load flow to full suspension flow increases with the increase in inclined angle. However, an inverse transition phenomenon occurs at intermediate inclined angle, where the full suspension flow inversely turns into particle bed load flow with the increase in injected velocity.

Abstract:
On the erosion due to inclined jets Some preliminary experiments and studies regarding scour processes on a mobile bed caused by inclined jets issuing from a sluice gate are presented. Tests with submerged tailwater conditions have been carried out using different flow and geometric conditions. The investigated experimental conditions included different jet Froude numbers, inclinations and tailwater conditions. The bed configuration has been measured during the whole scour hole evolution process until the achievement of a dynamic steady state, where sediment motion was still possible even though it did not allow for any persistent change in the scour and ridge shapes anymore. On the basis of the observed sediment motion, two different patterns of flow seem to develop under the investigated conditions: one where the main flow remains attached to the bottom of the channel and another where it oscillates between the aforementioned configuration and a surface jet. Some relevant parameters have been identified and used to plot graphs showing their correlation and trends.

Abstract:
Most research on the hydrodynamics and solids mixing of swirling fluidized beds has targeted applications relate to drying and combustion processes, with large mean particle diameters. A potential use of such reactors is in the area of catalyst regeneration to improve mixing. In the present study, the hydrodynamics and solids mixing behaviour of swirling fluidized beds were investigated for particles in Groups A and B of the Geldart classification. Three distributors were designed and fabricated in-house. They shared the same specifications, but differed in the orifice inclination angle (30, 45 and 90 to the horizontal). The effect of orifice angle on the hydrodynamics of a fluidized bed of glass beads was investigated. The study showed that, in an empty bed, the distributor pressure drop was lower for the inclined-hole distributors compared to the 90-hole distributor by a factor of 10%. In addition, bed pressure drop increased with the inclined-hole distributors as well with static bed height. Bed expansion was also investigated and found that in a shallow bed, the inclined-hole distributor led to less expansion compared to the 90-hole distributor. However, in a deep bed, the orifice angle had negligible influence on bed expansion. The minimum fluidization velocity was found to change with static bed height for the inclined-hole distributors, and it was also higher for steeper angles. Solids mixing was also explored, axial mixing for the 90-hole distributor and tangential mixing for all three distributors. Residence time distribution studies were conducted using phosphorescent tracer particles belonging to Group A, activated by ultraviolet light. The turnover time was estimated using the bubbling bed model and found to match the experimental results well. It was found that the probes installed at the walls of the fluidization column reduced the dense phase downward velocity. The tangential particle velocity was also estimated and was found to be highest for the 30-hole distributor, decreasing with increasing orifice angle. A dispersion model was used to describe tangential mixing for all three distributors which showed that the dispersion coefficient for the inclined-hole distributors was twice that for the 90-hole in a shallow bed.

The purpose of this study is to investigate wave reflections on smooth and varied porous inclined beds in a wave flume of Tainan Hydraulics Laboratory. Among the 585 tests, it was mainly categorized into two groups, which were those covered the entire inclined beds and those porous beds only covered the surf-zone region. The characteristics and reflection coefficients of waves propagate on porous beds of varied slopes, constructed material, porosities, the ratio of incident wave heights to thickness of constructed material and nonlineality were investigated.. Experimental results show that wave dissipation is influenced by porous inclined beds of varied material. The presented results also show that the larger the porosity is, the more wave energy would be dissipated. While nonlineality increases, the porosity increases with an decrease in influences of slope. Moreover, the ratio of incident wave heights to thickness of constructed material will influence the distribution of reflection coefficients on the porous inclined beds. The wave reflection influenced by incident wave height reveals more obviously on smooth beds. Finally, the distribution graghs of Ur combined with Hi、d、L and Cr yield that the wave dissipation of porous structure reveals more obviously subject to long waves.

Abstract:
Dams and barrages play a very vital role in the economy of a country by providing essential benefits like irrigation, hydropower, flood control, drinking water, recreation, etc. However, when these fail in rare conditions, these may cause catastrophic flooding in the downstream area resulting in huge loss to human life and property. The spillway is among the most important structures of a dam project. It provides the project with the ability to release excess or flood water in a controlled or uncontrolled manner to downstream to ensure the safety of the project. The surface of the spillway should also be such that it is able to withstand erosion or scouring due to the very high velocities generated during the passage of a flood through the spillway. So the safety of spillway against the scouring at downstream is also important. To prevent the scouring of the riverbed and failure of the hydraulic structure, energy dissipators are commonly used for the purpose of dissipating the excessive kinetic energy of flowing water downstream of hydraulic structures. An experimental study was conducted to understand the scouring pattern below downstream of the spillway. A rectangular flume of dimensions 6.0m(length)X0.30m(width)X0.60m(depth), four spillway models(ogee spillway, ski jump bucket, ogee spillway with subsidiary dam, ogee spillway with baffle wall) and locally available material to prepare bed were used in this study. A pitot tube was used to measure the flow velocity and discharge. To measure the pre-jump and post-jump for the calculation of energy loss point gauge was used. In this experimental study total 40 tests were conducted using same run time. The scour pattern (depth and length) were measured after each test run.

This paper is aimed to investigate the relationship between wave decay and the physical properties of porous bed. To achieve this, a series of experimental tests were conducted. In these tests, a total of four types of porous material and four material thickness were adopted, then wave decay over these porous beds were measured under various wave conditions. Based on experimental results, it is observed that the wave height decreases as the dimensionless progressive distance increases. Further, the wave-decay rate increases rapidly with increasing relative thickness of the porous bed as the relative thickness is smaller than 0.2. However, if the relative thickness becomes greater than 0.2, the wave-decay rate increases only slightly with increasing relative thickness. Therefore, it is realized that waves consume more energy on the porous bed within a relative thickness of 0.2 than within the deeper part. As for the porosity, it is indicated that the wave height reduces rapidly with increasing porosity. Finally, a regression analysis was conducted and a wave-decay formula was established relating to those factors such as dimensionless progressive distance, relative thickness, and porosity.

The purpose of this study is to discuss operating limitations of inclined circulating fluidized bed. With different conditions of inlet air and parameters of desiccants, minimum of circulating wind speed and related parameters can be found by experiments. And according the results of the experiments, the design method of fluidized bed can also be set out. First, by the observation of the paths between beds, the main reason causing the paths’ jamming can be conjectured to be the sphericity, the static electricity, the direction of the wind in the paths, the flow rate of desiccant particles in the paths and the filling height of desiccant. Besides, the parameters affecting the behavior of desiccant particles in the paths are the material density and strength of desiccants. Second, according to the results of the experiments, the parameter affecting minimum of circulating wind speed most is the average filling amount of desiccants per area, and it presents positive correlation. Finally, according to the results of the experiments and the relations between parameters of beds, the design method of fluidized beds can be set out.

The purpose of this study is to design an inclined circulating fluidized bed that maintains a proper humid indoor environment and be energy-efficient. With gravity, the design of particle channels and the characteristics of the fluidized bed, the system can adsorb water vapor continuously and steadily. This study first experimentally investigates the performance of the fluidized bed, both circular and square tube, under different operating air conditions. The results indicates that the adsorption capacity is increased with the raising relatvie humidity of the outside air and the raising regeneration temperature. Besides, under the condition of high regeneration temperature(50℃), there is little difference between the adsorption capacity of a circular tube and that of a square tube. Nevertheless, under low regeneration temperature(25℃), the adsorption performance of curcular tube is higher than that of the square tube. It’s because, compared to a square tube, the shape of a circular tube inherently increases the exchange rate of particles between the beds. This study also experimentally investigates the influence of a wedged-shape air baffle on the performance of the system, and then finds out the weight of particles with the highest adsorption rate. The results indicates that the total adsorption amount per hour per weight of particles increases with the baffle placement. The number 4 baffle of the circular beds (bottom thickness 4.7 cm, height 13 cm) with the weight of particles 495 g per bed has the highest total adsorption amount per hour per weight of particles, 0.512 kg/hr-kg. In this experiment, as the lower edge of the exit of the particle channels represents the baseline, the submerging height (the average height of the inclined particle plane in beds) is around 60% of the length between the lower edge and the higher edge of the exit of the particle channels. As for the square-tube beds, the number 4 baffle (bottom thickness 4.15 cm, height 13 cm) with 408 g weight of particles gives the highest adsorption result, 0.534 kg/hr-kg. Its submerging height is around 45% of the length between the lower/higher edges of the exit of the particle channels.

This research discusses the problem of inclined ground-sill downstream channel scouring with by using flume experiment and compares it with traditional ground-sills. Discussing the effect of inclined ground sill from the degree of river-bed scouring and setup experience equations for the largest sour hole, longest scour length and scour hole volume in comparison of erective ground-sills And use this information as the suggestion for future practical application. According to the result of the test we can realize: 1.When there is no structure roughness setup on the inclined ground-sill wall (where the board manning n roughness is about 0.006), the scale of scour hole is smaller than the traditional erective ground-sill and can reduce scouring volume up to 50%. 2.When the incline ground-sill wall Manning n is between 0.006~0.015, the scale of downstream channel scour hole would decrease with the increase of roughness ; but when manning n exceed 0.015, due to the effect of increase sediment roughness on the inclined ground-sill wall, the water stage raises and increase the downstream scouring scale. 3.The result of this experiment show that: When manning n is 0.015, the length of inclined ground-sill slope is 1.5 times wide of the relative channel width, and the slope of flume is 0.5 degree, the scour volume decrease could reach 85% of the erective ground-sills in average. It explains the development of controlling the scale of river-bed scour after river course construct declined ground sill.

Abstract:
Feeling like doing something is not the same as deciding to do it. When you feel like doing something, you are still free to decide to do it or not. You are having an inclination to do it, but you are not thereby determined to do it. I call this the moment of drama. This book is about what you are faced with, in this moment. How should you relate to the inclinations you “have,” given that you are free to “act on” them or not? To answer this question, we need an account of what sort of thing we are relating to, in this moment. But here we find a genuine philosophical problem. Our inclinations are forms of motivation, with respect to which we are distinctively passive. To be motivated is to be self-moved. But how can we be passive in relation to our own self-movement? Is our relation to our inclinations like that of rider to horse? Or is it like our relation to our own, spontaneous judgments or perceptions? I lay out three constraints on any theory of inclination, and I argue that familiar theories fail to meet them, because they make being inclined to φ‎ too similar or dissimilar to φ‎-ing. I then put forward the “inner animal” view, which holds that when you are merely inclined to act, the instinctive part of yourself is already active, while the rest of you is not. In this moment, your will is “at a crossroads.” You can humanize your inclination, or dehumanize yourself.

Abstract:
The field of positive organizational scholarship highlights the paradox that exists between the negative and the positive in organizations and in individuals. On the one hand, all living systems have a tendency toward, and flourish in the presence of, the positive. Physically, psychologically, emotionally, and socially human systems are inclined toward positive energy and away from negative energy. This is called the heliotropic effect. On the other hand, bad is stronger than good, and individuals and organizations respond more readily and more dramatically to the negative than to the positive. The negative disrupts more readily than does the positive. This chapter grounds this paradoxical phenomenon in academic literature and then reconciles their simultaneous opposite presence in organizations and individuals. Transcending this paradox leads to extraordinarily effective performance for individuals and for organizations.

Abstract:
Chapter 4 explores Lawrence’s writing of relationships after his direct engagements with Einsteinian ideas in 1921, seeking to ascertain both the extent and the nature of the impact which Einsteinian relativity had on his thinking. Other possible sources for Lawrence’s relativistic ideas are considered, in particular William James’s relativism. However, ultimately the chapter argues that Einstein’s direct impact can be seen in terms of both the language adopted by Lawrence and the theoretical framework behind his ‘theory of human relativity’. Although Lawrence’s writing of relationships does not change much after reading about Einsteinian relativity, he seems more inclined to theorize on this topic after 1921, as a consideration of his novels Kangaroo and Aaron’s Rod emphasizes. Lawrence’s engagement with relativity is also shown to be significantly different from that of other modernist writers, in that he uses relativity in order to explore the issue that interested him most: human relationships.

Full text
Abstract:
Calvinist jurist Johannes Althusius (1557–1638) developed what he called a ‘universal theory’ of law and politics for war-torn Europe. He called for written constitutions that separated the executive, legislative, and judicial powers of cities, provinces, nations, and empires alike and that guaranteed the natural rights and liberties of all subjects. To be valid, he argued, these constitutions had to respect the universal natural law set out in Christian and classical, biblical, and rational teachings of law, authority, and rights. To be effective, these constitutions had to recognize the symbiotic nature of human beings who are born with a dependence on God and neighbour, family and community, and who are by nature inclined to form covenantal associations to maintain liberty and community. Althusius left comprehensive Christian theory of rule of law and politics that anticipated many of the arguments of later Enlightenment theorists of social and government contracts.

Abstract:
Chapter 4 offered an answer to the hiddenness problem that depended on acceptance of a modest, but still robust doctrine of divine transcendence. But some will be inclined to resist that doctrine. The present chapter, therefore, sets aside that doctrine and offers an independent answer to the hiddenness problem. The chapter is devoted to explaining why divine love should not be identified with “ideal” human love. The upshot is roughly the same as that of Chapter 4, though by a different route: the hiddenness problem can get no rational purchase on us by way of philosophical reflection on our ordinary understanding of the nature of love. At best, the problem gains a foothold only through the negatively valenced love analogies that are suggested by certain characterizations of how God is behaving toward various kinds of people. The chapter concludes by briefly outlining how this latter issue will be addressed in subsequent chapters.

Abstract:
Wars often have unjust political subjugation as their aim. This raises the question, How much violence can we impose on those attempting to politically subjugate us? Just war theorists inclined to what has come to be called reductive individualism have argued that we can answer this question by determining how much violence you can impose on an individual wrongly attempting to prevent you from voting, or from political participation more broadly construed. Some have argued that the amount of violence we can permissibly impose in such a situation is decidedly sublethal. This in turn yields a largely pacifist response to the question of how much violence we can impose to avert political subjugation. This chapter argues that political subjugation involves a fundamental disrespect of a sort missed both by proponents of the pacifist response and by their detractors.

Abstract:
As this chapter suggests, country music’s success can be measured not just in records sales, but as based in nurturing an elaborate and committed fan culture. Through characteristic rituals and using new media and technology, the distance between production and consumption expands and contracts. The historical and close collaboration between the industry and country fandom makes the genre distinctive. The chapter also discusses country fan club culture, which assures inclined fans some chance for communalism and possible contact with artists themselves. The complex and changing relationship between the more formal media and trade organizations and the more informal club culture is another unique aspect to country music’s fandom. In addition, there is perhaps no better way to understand country fandom than two forms of interactions: “meet-and-greets” and the interactions in and around the annual CMA festival.

Abstract:
Why care whether there is a necessary being? The chapter opens with an explanation of how the question of whether there is a necessary being matters in theology, cosmology, and debates about fundamental ontology. It is shown that some of the most important questions in these fields depend in one way or another on whether there is a necessary being. Some reason is provided to be optimistic that it is possible to make progress on the question of whether there is a necessary being. Toward that end, the results of a survey (www.necessarybeing.com) are also given, which suggests that the vast majority of people, including skeptics of a necessary being, are inclined to find plausible certain premises in deductive arguments for the existence of a necessary being. The stage is set for a detailed presentation and analysis of those arguments.

Abstract:
Douglas A. Sweeney recapitulates the massive role of biblical reflection in Jonthan Edwards’ life and thought and then summarizes the chief contributions of this volume. He argues persuasively that students of Edwards need to attend closely to his “chief occupation”: biblical exegesis. Much work still needs to be done on this aspect of Edwards, and Sweeney offers suggestions about elements of Edwards’ exegetical endeavors requiring further attention. Those interested in Edwards’ work with modern higher criticism have much more work to do on his handling of the historicity of the Pentateuch, the scope of biblical prophecy, the synoptic problem, and more. Those inclined toward the contents of Edwards’ major treatises have far more to do on their relation to the Bible and what Edwards took to be the Bible’s theological claims. And all of us have more to do on Edwards’ biblical context and interlocutors, and the bearing of these sources on his preaching, teaching, and writing.

Abstract:
Demonstrations of animal memory were among the earliest experimental results obtained in psychology, but investigations of whether animals show metacognitive competencies are relatively new. Such investigations require innovative paradigms in which uncertainty can be created and empirically validated, methods by which nonverbal organisms can indicate their recognition of confidence or uncertainty, and systematic inquiry to determine whether such responses are externally, associatively generated or are subjective and metacognitive. This third point requires particular attention to balance competing considerations like anthropomorphism, parsimony, and interpretive errors, such as being too inclined to infer analogous mechanisms, or conversely to reject real demonstrations of animal metamemory by holding them to different evidentiary standards than is human metacognition. The results from numerous attempts to address these challenges are reviewed, yielding the overall conclusion that the capacity for metamemory and metacognition has been demonstrated at least by some animals in ways that defy low-level associative interpretation.

Abstract:
Abstract The accumulation of rock cuttings, proppant, and other solid debris in the wellbore due to inadequate cleanout remarkably impedes field operations. This article presents a new hole cleaning model, which calculates the Critical Transport Velocity (CTV) in conventional and fibrous fluids. The study is aimed to establish an accurate mechanistic model for optimizing wellbore cleanout in horizontal and inclined wells. The new CTV model is established to predict the initiation of bed particle movement during cleanout operations. The model is formulated considering the impact of fiber using a special drag coefficient (i.e. fiber drag coefficient), which represents the mechanical and hydrodynamic actions of suspended fiber particles and their network. The dominant forces acting on a single bed particle are considered to develop the model. Furthermore, to enhance the precision of the model, recently developed hydraulic correlations are employed to compute the average bed shear stress, which is required to determine the CTV. In horizontal and highly deviated wells, the wellbore geometry is often eccentric, resulting in the formation of flow stagnant zones that are difficult to clean. The bed shear stress in these zones is sensitive to the bed thickness. The existing wellbore cleanout models do not account for the variation in bed shear stress. Thus, their accuracy is limited when stagnant zones are formed. The new model addresses this problem by incorporating hydraulic correlations to account for bed shear stress variation with bed height. The accuracy of the new model is validated with published measurements and compared with the precision of an existing model. The use of fiber drag and bed shear stress correlations has improved model accuracy and aided in capturing the contribution of fiber in improving wellbore cleanout. As a result, for fibrous and conventional fluids, the predictions of the new model have demonstrated good agreement with experimental measurements and provided better predictions than the existing model. Model predictions show a noticeable reduction in fluid circulation rate due to the addition of a small quantity of fiber (0.04% w/w) in the fluid. In addition, results show that the existing model over predicts the cleaning performance of both conventional and fibrous fluids.

Abstract Epithelia of conducting airways is lined with a layer of mucus above a layer of serous fluid. Mucus is a viscoelastic gel, while the serous layer is identified as “watery”. In normal airways, the mucociliary transport system forms the primary basis for clearance of mucus. Dehydration results in the disappearance of serous layer and impairs the mucociliary clearance. For these persons two-phase gas-liquid flow and cough become the dominant mechanisms.

Abstract:
Abstract Severe accidents (SA) in Light Water Reactors (LWRs) consist of a sequence of thermal-hydraulic events which leads to situations that progress beyond design-based accidents (DBAs), and involve significant core degradation which threatens the integrity of the containment boundary. As part of the coolability assessment under accident conditions, the geometrical configuration of the debris bed is important. Here, experimental study was performed to investigate the formation of debris beds under the influence of a two-phase flow induced by steam generation due to the decay heat of the debris bed on an inclined bottom surface. Current study is an extension to the previous work of Kim et al. (2016) in which the previous model for development of an ex-vessel corium debris bed will be modified by incorporating the effect of bottom surface inclinations. This paper reports the experimental part of the study describing the spreading of the debris bed in terms of two-phase flow, debris injection parameters, and bottom inclined surface geometrical parameters is discussed.

Abstract:
Solid particle transport in pipelines by fluids is widely encountered in energy industry processes, such as oil production, drilling of horizontal and inclined wells and mining. In contrast to the intensive research effort that has investigated solid transport in horizontal pipelines, limited studies have been published on solid transportation mechanism generated from an initial stationary particle bed in inclined pipes. Consequently the underlying mechanisms responsible for pipe inclination influence on bed-load transport phenomena have not been extensively assessed, particularly for gas-liquid conveying of solid particles. This paper presents an experimental investigation on the influence hydraulic and two phase (gas-liquid) flows on sand dune transportation resulting from a stationary flat bed as a function of (i) pipe inclination, (ii) gas liquid flow rate and (iii) initial sand bed thickness. Experiments were undertaken in a laboratory environment using a 14 m long transparent Plexiglas loop of 24 mm internal diameter to permit optical access. The three phases used were water, air and sand. High speed digital photography was employed to study the flow phenomenon and characteristics of sand bed transportation for the analysis variables (i) to (iii) under consideration. For hydraulic conveying of solid particles, it was found that 1° upward pipe inclination had negligible influence on both the flow phenomenon and solid-liquid flow pattern transition. In contrast, for gas-liquid conveying of solid particles, pipe inclination resulted in considerably different transport phenomena relative to that observed for the horizontal orientation. Differences such as backward bed movement and enhanced particle suspension were observed, and found to be highly gas-liquid ratio dependent. These measurements provide fundamental insights into the influence of upward pipe inclination on bed-load mode solid transportation in a closed conduit.

Abstract:
The understanding of sand particle transport by fluids in pipelines is of importance for the drilling of horizontal and inclined hydrocarbon production wells, topside process facilities, infield pipelines, and trunk lines. Previous studies on hydraulic conveying of sand particles in pipelines have made significant contributions to the understanding of multiphase flow patterns, pressure drop and particle transport rate in horizontal pipelines. However, due to the complexity of the flow structure resulting from liquid-sand interactions, the mechanisms responsible for bed-load transport flow for hydraulic conveying of sand particles have not been extensively studied in inclined pipelines. This paper presents an experimental investigation of hydraulic conveying of sand particles resulting from a stationary flat bed in both horizontal and +3.6 degree upward inclined pipelines. The characteristics of sand transportation by saltation from an initial sand bed are experimentally visualized using a transparent Plexiglas pipeline and high-speed digital photography. The dune formation process is assessed as a function of pipeline orientation. Based on the visualized dune morphology, pipeline inclination is found to have a significant influence on hydraulic conveying of sand dune dynamics (i.e., dune velocity), as well as sand dune geometry (i.e., dune pitch and characteristic dune angles).

Full text
Abstract:
Knowledge of flow regime, holdup and pressure drop is needed in order to design gas and oil pipelines confidently and to minimize construction and operating costs. Previous public studies of two-phase flow in inclined pipes have used small diameter pipes two inches in diameter or less, and have primarily used air and water as the working fluids at low pressure (near one atmosphere). Present design methods are based upon the results of these experiments. In most advanced analyses available today, the flow regime transition is governed by a Froude number, the balance between inertial and buoyancy forces. The primary objective of the work has been to obtain experimental data to challenge the present two-phase flow analysis methods for large pipe size, high gas density, and pipe inclination. Present analysis and design methods for two-phase flow in pipelines are based on correlations of data from small pipes of order 2-inches diameter or less, for air-water flows at pressures near one atmosphere. To achieve this objective, Creare performed experiments in an existing test facility with a special test section assembled for this project. Pipe diameter and gas density are closer to prototypical oil and gas pipeline conditions than previous experiments reported in the literature. The key experimental results include flow regime observations, pressure drops, and holdup measurements. The instrumentation in the test facility allows detailed characteristics of the flow such as slug velocity, slug frequency, liquid film velocity, and slug length to be measured in the slug flow regime.

Full text
Abstract:
High soil loads on buried pipelines can lead to unacceptably high pipeline strains developed in response to permanent ground displacement. Common causes of permanent ground displacement are related to slope instability as a result of heavy precipitation or ground subsidence. In addition, several permanent ground displacement hazards are related to earthquakes including surface fault displacement, triggered landslide movement, surface ground settlement related to liquefaction, and lateral spread displacement. Result: Four specific areas of investigation were completed: 1.Performed baseline tests in moist sand to confirm minimal difference in horizontal soil restraint between moist and dry sand. 2.Performed tests to gauge the variation in horizontal load reduction with separation between the pipe and an inclined trench wall lined with two layers of geotextile. 3.Performed tests in compacted 19 mm (0.75 in) minus sand and crushed limestone (referred to locally in British Columbia as road mulch) to attempt to provide larger difference between horizontal forces developed with and without lining a trench wall with geotextile. 4.Performed tests to attempt to confirm oblique horizontal-axial soil restraint behavior reported in small-scale tests and centrifuge tests. Benefit: Rather than undertake further physical testing to better understand how the presence of single or dual layers of geotextile fabric changes the mechanisms by which soil restraint develops for horizontal ground displacement, future efforts should focus on numerical simulation preferably using discrete element methods. Until full-scale test data are available to confirm consistent prediction of oblique horizontal-axial soil restraint, the practice of treating horizontal and axial soil springs independently in the analysis of buried pipeline response to ground displacement, as is the current practice, should be maintained.
