Download or read book A Study of Two phase Flow in a Large Diameter Horizontal Pipeline and the Measurement of Interfacial Level Gradient in Smooth Stratified Flow Conditions written by Essaied Masoud Ali and published by . This book was released on 1992 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the behaviour of two-phase flow in large diameter horizontal pipelines. The study was divided into two main parts: (i) General two-phase flow in 203 mm diameter pipeline, where the pressure drop and void fraction were measured. The pressure drop was measured using 23 bottom tapping points along a 34 m test section. The results were compared with six well known pressure drop models; these models did not allow for diameter size effect, it was therefore not surprising that good agreement was not achieved. A traversing y-ray apparatusw as designed and constructed for the measurements of void fraction. Void fraction measurements were compared with geometrical void fraction calculation, and very satisfactory agreements were obtained. The apparatus was also tested under a different number of chordal positions (steps) to determine the influence of the number of steps on the accuracy of the results. The void fraction results were compared with nine correlations found in the literature; the effect of pipe size was clear. A flow pattern map was also drawn for a 203 mm pipeline, which covered all the possible flow patterns (annular flow could not be obtained in this size of pipe, with the available air supply), and compared with three well known flow pattern maps, where a little agreement was found. (ii) The measurement of interfacial level gradient in the smooth stratified flow conditions. Two depth gauges (probes) were designed, constructed and calibrated for the measurement of the water level change along the test section. The two probes were placed 12 metres apart in the test section, where the flow conditions considered settled. The measurement accuracy of the probes was within 1 mm of liquid height, i. e. less than 1%. Two theoretical models in the field of stratified flow were tested and then modified to improve their ability to predict the present data, and perhaps 11 other data obtained from large diameter pipelines. A model based on the present set of data, following Bishop et. al (1986) approach was proposed, which predicts the present data within RMS of 8%.

Book Modelling and Experimentation in Two Phase Flow

Download or read book Modelling and Experimentation in Two Phase Flow written by Volfango Bertola and published by Springer. This book was released on 2014-05-04 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an up-to-date review of recent advances in the study of two-phase flows, with focus on gas-liquid flows, liquid-liquid flows, and particle transport in turbulent flows. The book is divided into several chapters, which after introducing basic concepts lead the reader through a more complex treatment of the subjects. The reader will find an extensive review of both the older and the more recent literature, with abundance of formulas, correlations, graphs and tables. A comprehensive (though non exhaustive) list of bibliographic references is provided at the end of each chapter. The volume is especially indicated for researchers who would like to carry out experimental, theoretical or computational work on two-phase flows, as well as for professionals who wish to learn more about this topic.

Book Computational Fluid Dynamics Model of Two phase Heavy Oil and Air Flow in a Horizontal Pipe

Download or read book Computational Fluid Dynamics Model of Two phase Heavy Oil and Air Flow in a Horizontal Pipe written by Nicholas E. Sanders and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of heavy oil resources is becoming more prevalent as the conventional resources of the world continue to deplete. These heavy oil resources are being produced from horizontal wells and need to be transported in pipeline to processing facilities as a two-phase flow. Two-phase flow is important to the oil industry with the general focus being placed on light oil or water and gas flows. With little work having been done on two-phase heavy oil flow this study will examine these two-phase flows by recreating experimental data generated for heavy oil and air flow in a 1.5-inch diameter pipe and expand this data to include larger 2.875-inch and 3.5-inch pipes. A computational fluid dynamics model was generated to mimic the 1.5-inch diameter pipe used in the experiments. This model was validated for laminar and turbulent flow by using the same heavy oil properties from the original experiment and air respectively. The model was then run to simulate the given two-phase oil-air flows provided from the experimental data for the flow velocities that had pressure drop and liquid holdup data available. The two-phase results were compared to both the experimental data and the Beggs and Brill values for both pressure drop and liquid holdup. A 2.875-inch and 3.5-inch model were generated and the same process was followed for laminar and turbulent validation and then with a subset of four two-phase flow velocities. Without the availability of experimental data for the two larger size pipes the two-phase results were only compared to the Beggs and Brill values. Overall the results showed a good correlation to the laminar and turbulent flow in all three models with the turbulent flow showing the largest error for the pressure drop when the flow was in the laminar to turbulent transition zone for Reynolds numbers. The two-phase results showed to be in between the experimental and Beggs and Brill method values for the original 1.5-inch model and showed that as the gas flow velocity increased in the system the error grew for all three models. Given that the Beggs and Brill method values were generated based on experiments for water-air flow in a 1.0-inch pipe the values for the pressure drop in the 2.875-inch pipe and the 3.5-inch pipe were not unexpected and seemed to match well with an extrapolation of the experimental values. This study shows that a model can be generated to examine the two-phase flow behavior in horizontal sections of well and in pipelines on a computational basis. While these models are time consuming to generate and run with the increase in computing capacity available easily they can become more suitable than generating experimental setups for finding the same information. There will need to be more work done on heavy oil two-phase flow and additional experiments run for larger size pipes and two-phase flow to help tune these models but they do show promise for the future.

Book Two Phase Gas Liquid Flow in Pipes with Different Orientations

Download or read book Two Phase Gas Liquid Flow in Pipes with Different Orientations written by Afshin J. Ghajar and published by Springer Nature. This book was released on 2020-03-14 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides design engineers using gas-liquid two-phase flow in different industrial applications the necessary fundamental understanding of the two-phase flow variables. Two-phase flow literature reports a plethora of correlations for determination of flow patterns, void fraction, two- phase pressure drop and non-boiling heat transfer correlations. However, the validity of a majority of these correlations is restricted over a narrow range of two -phase flow conditions. Consequently, it is quite a challenging task for the end user to select an appropriate correlation/model for the type of two-phase flow under consideration. Selection of a correct correlation also requires some fundamental understanding of the two-phase flow physics and the underlying principles/assumptions/limitations associated with these correlations. Thus, it is of significant interest for a design engineer to have knowledge of the flow patterns and their transitions and their influence on two-phase flow variables. To address some of these issues and facilitate selection of appropriate two-phase flow models, this volume presents a succinct review of the flow patterns, void fraction, pressure drop and non-boiling heat transfer phenomenon and recommend some of the well scrutinized modeling techniques.
