This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Slug flow can emerge as a factor in several industrial processes, especially in the oil and gas (O&G) industry. However, because of the complications that are inherent in multiphase flow, finding or developing a viable analysis tool has thus far proven elusive. For the past few decades, computational fluid dynamics (CFD) has served as the preferred approach in the flow analysis of single phase flow, yet it is only now beginning to be used in multiphase flow. Therefore, if CFD is to be adopted on a larger scale in the (O&G) industry, it is imperative that we first explore the wide variety of models currently existing in the commercial realm. This thesis investigates the commercial CFD package ANSYS 16.2 analysis of (air-water slug flow) and (water-sand slurry flow) inside a horizontal pipe (2-15 m long with a 0.05-0.059 m internal diameter) and an annular pipe (2- 4.5 m long, 0.02- 0.088 m inner and 0.04-0.12 m outer diameter). A range of two-phase air/water flow simulations is carried out using the Eulerian model with the Reynolds Stress Model (RSM), and the volume of fluid (VOF) model with the Shear-Stress-Transport (SST) model option of turbulence. The aim is to simulate a range of fluid velocities between 1.66 and 7 m/s and a range of gas velocities between 0.55 and 11 m/s. Additional investigations include comparing CFD predictions along with experimental measurements in the literature and performing sensitivity studies. In the present work, the impact from fluid-structure interaction (FSI) is demonstrated by using a 2-way coupling in ANSYS, effectively joining CFD and structural analysis. At the same time, stress and pressure changes are measured, along with the deformational structural response arising from unsteady multiphase flow. It is hoped that the outcome of this study will assist engineers and researchers in making better decisions in terms of operation, design, and sizing of two-phase flow systems, as these systems have broad and promising applications in subsea (O&G) pipelines.

Available in PDF, EPUB and Kindle. Book excerpt: Together with turbulence, multiphase flow remains one of the most challenging areas of computational mechanics and experimental methods and numerous problems remain unsolved to date. Multiphase flows are found in all areas of technology, at all length scales and flow regimes. The fluids involved can be compressible or incompressible, linear or nonlinear. Because of the complexity of the problems, it is often essential to utilize advanced computational and experimental methods to solve the complex equations that describe them. Challenges in these simulations include modelling and tracking interfaces, dealing with multiple length scales, modelling nonlinear fluids, treating drop breakup and coalescence, characterizing phase structures, and many others. Experimental techniques, although expensive and difficult to perform, are essential to validate models. This book contains papers presented at the Fifth International Conference on Computational Methods in Multiphase Flow, which are grouped into the following topics: Multiphase Flow Simulation; Interaction of Gas, Liquids and Solids; Turbulent Flow; Environmental Multiphase Flow; Bubble and Drop Dynamics; Flow in Porous Media; Heat Transfer; Image Processing; Interfacial Behaviour.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study analyzes the influence of the physical properties of Newtonian and non-Newtonian fluids, such as density, effective viscosity and surface tension, as well as operational parameters of the piping, such as diameter, length and inclination angle on the drift velocity for two-phase gas-liquid flow. This study comprises experimental and Computational Fluid Dynamic (CFD) approaches. The simulation model was calibrated through a mesh independence test, which considered experimental and literature data as benchmark, and was divided in three sections based on the viscosity of the fluid and the positioning of the pipeline. The results obtained through the CFD model showed good agreement with the experimental data gathered for the present study, keeping the experimental deviations under 30% for all cases. The relationship between the Froude number (Fr) and Viscosity number (Nvis) was studied and an inverse exponential pattern was found for all the parameters and fluids tested. Additionally, the relation observed between Fr and Nvis for a horizontal setting on Newtonian fluids had good resemblance with the models proposed in literature, predicting accurately a decreasing behavior of the drift velocity for increasing viscosity. The data gathered for all fluids on the drift velocity's behavior against operational parameters showed the influence of the governing forces for each case based on a dimensionless analysis using Etvos (Eo) and Reynolds (Re) numbers. For dominant capillary or viscous forces, the drift velocity changed with the variation of these parameters. However, it was found that for dominant inertial and gravitational forces, the drift velocity maintained a constant value regardless of the operational settings. Finally, it was observed that the rheological nature of the non-Newtonian fluids has a significant influence on the drift velocity's behavior, deviating its patterns from the Newtonian fluids as the effective viscosity changes.

Book excerpt: Slurry Flow: Principles and Practice describes the basic concepts and methods for understanding and designing slurry flow systems, in-plan installations, and long-distance transportation systems. The goal of this book is to enable the design or plant engineer to derive the maximum benefit from a limited amount of test data and to generalize operating experience to new situations. Design procedures are described in detail and are accompanied by illustrative examples needed by engineers with little or no previous experience in slurry transport. The technical literature in this field is extensive: this book facilitates its use by surveying current research results and providing explanations of mechanistic flow models. This discussion of background scientific principles helps the practitioner to better interpret test data, select pumps, specify materials of construction, and choose measuring devises for slurry transport systems. The extensive range of topics covered in Slurry Flow: Principles and practice includes slurry rheology, homogeneous and heterogeneous slurry flow principles, wear mechanisms, pumping equipment, instrumentation, and operating aspects.
