A powerful new monograph from an aerodynamicist reviewing modern conventional aerodynamic approaches, this volume covers aspects of subsonic, transonic and supersonic flow, inverse problems, shear flow analysis, jet engine power addition, engine and airframe integration, and other areas, providing readers with the tools needed to evaluate their own ideas and to implement the newer methods suggested in this book. This new book, by a prolific fluid-dynamicist and mathematician who has published more than twenty research monographs, represents not just another contribution to aerodynamics, but a book that raises serious questions about traditionally accepted approaches and formulations, providing new methods that solve longstanding problems of importance to the industry. While both conventional and newer ideas are discussed, the presentations are readable and geared to advanced undergraduates with exposure to elementary differential equations and introductory aerodynamics principles. Readers are introduced to fundamental algorithms (with Fortran source code) for basic applications, such as subsonic lifting airfoils, transonic supercritical flows utilizing mixed differencing, models for inviscid shear flow aerodynamics, and so on. These are models they can extend to include newer effects developed in the second half of the book. Many of the newer methods have appeared over the years in various journals and are now presented with deeper perspective and integration. This book helps readers approach the literature more critically. Rather than simply understanding an approach, for instance, the powerful "type differencing" behind transonic analysis, or the rationale behind "conservative" formulations, or the use of Euler equation methods for shear flow analysis when they are unnecessary, the author guides and motivates the user to ask why and why not and what if. And often, more powerful methods can be developed using no more than simple mathematical manipulations. For example, Cauchy-Riemann conditions, which are powerful tools in subsonic airfoil theory, can be readily extended to handle compressible flows with shocks, rotational flows, and even three-dimensional wing flowfields, in a variety of applications, to produce powerful formulations that address very difficult problems. This breakthrough volume is certainly a "must have" on every engineer's bookshelf.

Multiprobe Pressure Testing and Reservoir Characterization: Pressure Transient, Contamination, Liquid and Gas Pumping Analysis provides much-needed three-dimensional pressure transient simulators for job planning and data interpretation in well logging. Discussions cover fundamental concepts, present fluid sampling, pressure transient and contamination analysis; physical concepts and numerical approaches; and multiprobe model formulations and validations. Other sections cover four-probe algorithms, including conventional, overbalanced, and underbalanced drilling applications. The final section addresses triple-probe algorithms, which includes coupled models for pressure and contamination convergence acceleration. Notably, a further chapter explains how the multiprobe tool's focus on characterizing permeability will promote better use of the reservoir as well as assist with energy storage in underground rock, demonstrating how multiprobe tools also facilitate the energy transition from fossil fuels to sustainable geothermal energy. - Reviews present day needs, tool operations, and analysis methods, along with numerous practical examples and applications - Develops a suite of mathematical models, algorithms, and software from first principles - Explains, in detail, how multiprobe pressure logging is superior to using conventional sensors because direct, accurate reservoir characteristics support energy-efficient geothermal designs - Provides an alternative look at the investigation of unconventional reservoirs, not only in terms of hydrocarbon production, but also with carbon and energy storage in mind

For the purpose of publication of these Proceedings, the original conference programme has been rearranged to provide a more logical sequence of presentation. The beginning sections give the inaugural speech and the six keynote addresses which were delivered at the opening plenary session. Following these are the working papers, published more or less in the same sequence in which they were presented in the original programme. The order of presentation does not necessarily emphasise the importance of any one aspect of the Arctic Systems over others. The final reports of the six working groups and their conclusions and recommendations are edited in such a manner as to present them in a standardised format for easy comprehension. The editors accept responsibility for any distortion inadvertently introduced in the summarising and editing processes. Later sections of the Proceedings give a background to the Conference organization and deliberations, and an independent critique of the meeting. The directors and those who attended the Conference were conscious of the debt of gratitude owed by them to the Conference chairmen, rapporteurs, authors of working papers, and many individuals for their contributions to the success of the meeting. We wish to thank them and it is a pleasure to record their names in these Proceedings. Inaugural Speaker Dr. J. Rennie Whitehead, Canada Banquet Guest Speaker Honourable Mr. T. Alex Hickman, Canada Keynote Addresses Mr. C. Bornemann, Denmark Dr. A.E. Collin, Canada Dr. R.E. Francois, U.S.A.

Mathematically rigorous, computationally fast, and easy to use, this new approach to electromagnetic well logging gives the reservoir engineer a new dimension to MWD/LWD interpretation and tool design Almost all publications on borehole electromagnetics deal with idealizations that are not acceptable physically. On the other hand, “exact models” are only available through detailed finite element or finite difference analysis, and more often than not, simply describe case studies for special applications. In either case, the models are not available for general use and the value of the publications is questionable. This new approach provides a rigorous, fully three-dimensional solution to the general problem, developed over almost two decades by a researcher familiar with practical applications and mathematical modeling. Completely validated against exact solutions and physics-based checks through over a hundred documented examples, the self-contained model (with special built-in matrix solvers and iteration algorithms) with a “plain English graphical user interface” has been optimized to run extremely fast – seconds per run as opposed to minutes and hours – and then automatically presents all electric and magnetic field results through integrated three-dimensional color graphics. In addition to state-of-the-art algorithms, basic "utility programs" are also developed, such as simple dipole methods, Biot-Savart large diameter models, nonlinear phase and amplitude interpolation algorithms, and so on. Incredibly useful to oilfield practitioners, this volume is a must-have for serious professionals in the field, and all the algorithms have undergone a laborious validation process with real use in the field.

Despite their variety, the vibration phenomena from many different engineering fields can be classified into a relatively few basic excitation mechanisms. The classification enables engineers to identify all possible sources of excitation in a given system and to assess potential dangers. This graduate-level text presents a synthesis of research results and practical experience from disparate fields in the form of engineering guidelines. It is particularly geared toward assessing the possible sources of excitation in a flow system, in identifying the actual danger spots, and in finding appropriate remedial measures or cures. Flow-induced vibrations are presented in terms of their basic elements: body oscillators, fluid oscillators, and sources of excitation. By stressing these basic elements, the authors provide a basis for the transfer of knowledge from one system to another, as well as from one engineering field to another. In this manner, well-known theories on cylinders in cross-flow or well-executed solutions from the field of wind engineering--to name just two examples--may be useful in other systems or fields on which information is scarce. The unified approach is broad enough to permit treatment of the major excitation mechanism, yet simple enough to be of practical use.
