Transport by Pipelines and Its Optimization: A Sustainable Approach to the Design (Petroleum Engineering)

by Pablo Druetta Remo Frabotta Gustavo Luis Cavallo

This textbook introduces pipeline design, one of the most efficient techniques for mass and energy transport available today. The global economy heavily relies on pipelines. However, designing a pipeline is more complex than it might seem; it involves many technical and economic factors that must work together to create an optimized system. The book begins with basic concepts of pipelines, including a description of the materials used, heat transfer between the system and medium, and the main components of pumping and compression stations, which are vital for the subsequent chapters. It then presents a simple yet detailed overview of these factors and introduces a mathematical methodology that combines them to deliver an optimized pipe design, minimizing costs and reducing energy consumption. The book also covers the transient verification of this design using well-known balance equations and material property relationships for both incompressible and compressible fluids, to validate the initial design. Finally, the book explores the analysis of multiphase pipelines, where the goal is to transport a particular material (e.g., solid) using a different medium (e.g., air or water).

Transport Development in Asian Megacities: A New Perspective

by Shigeru Morichi Surya Raj Acharya

The rapid growth of the Asian urban population concentrates on a few large cities, turning them into giant megacities. Despite new theoretical insights into the benefits of megacities, the emerging Asia is facing a daunting challenge concerning the management of infrastructure and services in their megacities. The deteriorating urban mobility is the most difficult challenge with respect to the sharp increase in vehicle numbers and to inadequate and poorly managed road infrastructure. Public transport, a sustainable mode of mobility, is subjected to a vicious cycle of poor service, decreasing ridership and lower investment. Despite various policy initiatives, the situation has not improved. The scale and growth pattern of Asian megacities have distinctive features which generate a unique set of challenges and opportunities. New perspectives are needed to effectively address the transportation problems making the best use of available opportunities. This book, which is a result of an international collaborative research, addresses these challenges by providing insightful analysis and novel viewpoints.

Transport Efficiency and Safety in China (Population, Regional Development and Transport)

by Pengjun Zhao Liangen Zeng

This book is the first comprehensive analysis of transport efficiency in China. It presents a series of rigorous empirical analysis for the operation and environmental efficiencies of major transport sectors, including highway, railway, civil aviation, and waterway. It also evaluates transport safety of China. The book innovatively employs a DEA model based on Epsilon measures (EBM) to evaluate transport efficiency and an EBM DEA model with undesirable outputs to calculate transport environmental efficiency. The factors of transport efficiency are quantitatively studied, including economic growth, social transition, and technology changes. Also, China's policies aimed at improving transportation efficiency are evaluated.The theoretical analyses and discussions would enhance our existing knowledge of the changes and determinants of transport system’s efficiency in a context of rapid urbanization, industrialization, and marketization in China. The findings of the existing policy evaluation would bring fresh evidences for transport policy performances to both scholars and politicians. In particular, it shows policymakers the experiences or lessons of how to create an efficient transport system in order to save energy use, reduce GHGs emissions, and improve social security. This book is of great interest to scholars interested in sustainable transport, regional planning and development, environmental policy and is relevant to China and other developing countries.

It also presents the main strategies of the Monte Carlo method, as well as numerous comparisons between simulation results and the experimental data available in the literature. Furthermore it provides readers with all the information they need in order to write their own Monte Carlo code and to compare the obtained results with the many numerical and experimental examples presented throughout the book. An extended and updated third edition of a work published in 2014 (first edition) and in 2017 (second edition) on the application of the Monte Carlo method to the transport of fast electrons in solids, this book includes, as novel topics, the theory of polarized electron beams (i.e. density matrix and spin polarization), the study of elastic scattering by molecules, a classical treatment of the Bethe-Bloch stopping power, a simple derivation of the f- and ps-sum rules, the Vicanek and Urbassek formula for the calculation of the backscattering coefficient, the Wolff theory describing the secondary electron spectra, and fundamental aspects of the interactions between electrons beams and solid targets. Further, it describes a completely analytical approach (the so-called multiple reflection method) for calculating the absorbed, backscattered, and transmitted fractions of electrons from unsupported and supported thin films. It also discusses recent applications of the Monte Carlo method.

Transport of Energetic Electrons in Solids: Computer Simulation with Applications to Materials Analysis and Characterization (Springer Tracts in Modern Physics #290)

by Maurizio Dapor

This book describes the computational methods most frequently used to deal with the interaction of charged particles, notably electrons, with condensed matter. Both elastic and inelastic scattering phenomena are discussed, and methods for calculating the relevant cross sections are explained in a rigorous but simple way. It provides readers with all the information they need in order to write their own Monte Carlo code and to simulate the transport of fast particles in condensed matter. Many numerical and experimental examples are presented throughout the book.The updated and extended fourth edition features ab initio methods for calculating dielectric function and energy loss function. Non-relativistic partial wave expansion method for calculating the differential elastic scattering cross section is also included in this new edition. It represents a very useful introduction to the relativistic partial wave expansion method, i.e., to the Mott theory, already discussed in the previous editions of this book. Further details about the effects of spin-polarization on the differential elastic scattering cross section are included in this new edition. The multiple reflection method is extended to the general case of a system composed of a set of layers of different materials and thicknesses. Analytical expressions are provided for calculating the backscattering coefficient of multilayers. New results are presented, notably about Monte Carlo simulations of reflection electron energy loss spectra and of the radial dose deposited along the track of ions impinging on materials.

Transport Phenomena Fundamentals (Chemical Industries)

by Joel L. Plawsky

The fourth edition of Transport Phenomena Fundamentals continues with its streamlined approach to the subject, based on a unified treatment of heat, mass, and momentum transport using a balance equation approach. The new edition includes more worked examples within each chapter and adds confidence-building problems at the end of each chapter. Some numerical solutions are included in an appendix for students to check their comprehension of key concepts. Additional resources online include exercises that can be practiced using a wide range of software programs available for simulating engineering problems, such as, COMSOL®, Maple®, Fluent, Aspen, Mathematica, Python and MATLAB®, lecture notes, and past exams. This edition incorporates a wider range of problems to expand the utility of the text beyond chemical engineering. The text is divided into two parts, which can be used for teaching a two-term course. Part I covers the balance equation in the context of diffusive transport—momentum, energy, mass, and charge. Each chapter adds a term to the balance equation, highlighting that term's effects on the physical behavior of the system and the underlying mathematical description. Chapters familiarize students with modeling and developing mathematical expressions based on the analysis of a control volume, the derivation of the governing differential equations, and the solution to those equations with appropriate boundary conditions. Part II builds on the diffusive transport balance equation by introducing convective transport terms, focusing on partial, rather than ordinary, differential equations. The text describes paring down the full, microscopic equations governing the phenomena to simplify the models and develop engineering solutions, and it introduces macroscopic versions of the balance equations for use where the microscopic approach is either too difficult to solve or would yield much more information that is actually required. The text discusses the momentum, Bernoulli, energy, and species continuity equations, including a brief description of how these equations are applied to heat exchangers, continuous contactors, and chemical reactors. The book introduces the three fundamental transport coefficients: the friction factor, the heat transfer coefficient, and the mass transfer coefficient in the context of boundary layer theory. Laminar flow situations are treated first followed by a discussion of turbulence. The final chapter covers the basics of radiative heat transfer, including concepts such as blackbodies, graybodies, radiation shields, and enclosures.

Transport Phenomena in Multiphase Flows

by Roberto Mauri

This textbook provides a thorough presentation of the phenomena related to the transport of mass, momentum and energy. It lays all the basic physical principles, then for the more advanced readers, it offers an in-depth treatment with advanced mathematical derivations and ends with some useful applications of the models and equations in specific settings. The important idea behind the book is to unify all types of transport phenomena, describing them within a common framework in terms of cause and effect, respectively represented by the driving force and the flux of the transported quantity. The approach and presentation are original in that the book starts with a general description of transport processes, providing the macroscopic balance relations of fluid dynamics and heat and mass transfer, before diving into the mathematical realm of continuum mechanics to derive the microscopic governing equations at the microscopic level. The book is a modular teaching tool and can be used either for an introductory or for an advanced graduate course. The last 6 chapters will be of interest to more advanced researchers who might be interested in particular applications in physics, mechanical engineering or biomedical engineering. All chapters are complemented with exercises that are essential to complete the learning process.
