Download or read book Unsteady state Fluid Flow written by E.J. Hoffman and published by Elsevier. This book was released on 1999-07-02 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ubiquitous examples of unsteady-state fluid flow pertain to the production or depletion of oil and gas reservoirs. After introductory information about petroleum-bearing formations and fields, reservoirs, and geologic codes, empirical methods for correlating and predicting unsteady-state behavior are presented. This is followed by a more theoretical presentation based on the classical partial differential equations for flow through porous media.Whereas these equations can be simplified for the flow of (compressible) fluids, and idealized solutions exist in terms of Fourier series for linear flow and Bessel functions for radial flow, the flow of compressible gases requires computer solutions, read approximations. An analysis of computer solutions indicates, fortuitously, that the unsteady-state behavior can be reproduced by steady-state density or pressure profiles at successive times. This will demark draw down and the transition to long-term depletion for reservoirs with closed outer boundaries.As an alternative, unsteady-state flow may be presented in terms of volume and surface integrals, and the methodology is fully developed with examples furnished. Among other things, permeability and reserves can be estimated from well flow tests.The foregoing leads to an examination of boundary conditions and degrees of freedom and raises arguments that the classical partial differential equations of mathematical physics may not be allowable representations. For so-called open petroleum reservoirs where say water-drive exists, the simplifications based on successive steady-state profiles provide a useful means of representation, which is detailed in the form of material balances.Unsteady-State Fluid Flow provides:• empirical and classical methods for correlating and predicting the unsteady-state behavior of petroleum reservoirs• analysis of unsteady-state behavior, both in terms of the classical partial differential equations, and in terms of volume and surface integrals• simplifications based on successive steady-state profiles which permit application to the depletion of both closed reservoirs and open reservoirs, and serves to distinguish drawdown, transition and long-term depletion performance.

Download or read book Catalytic Processes Under Unsteady State Conditions written by Y.S. Matros and published by Elsevier. This book was released on 1988-12-01 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with catalytic processes under forced non-steady-state conditions. It demonstrates, both theoretically and practically, that forced non-steady-state processes are highly efficient compared with steady-state processes, and illustrates this with a wealth of practical examples.The first part of the book describes the theoretical and experimental basis of efficient processes, mathematical models of non-steady-state processes in reactors, influence of a non-steady-state catalyst surface, problems of optimization, the theory of a heat front in the fixed catalyst bed, and methods to create efficient cyclic regimes. The second part considers the following processes: sulphur dioxide oxidation in sulphuric acid production, cleaning of effluent gases from toxic impurities, production of high-potency heat, ammonia and methanol synthesis etc.The book will appeal to many readers: chemical engineers (especially in the field of mathematical modelling of reactors with a fixed catalyst bed); personnel of chemical plants and machine-manufacturing companies dealing with maintenance and installation of catalytic reactors; specialists in detoxification of the effluents from organic admixtures and carbon monoxide; students of technical colleges and universities
Download or read book Unsteady State Processes in Catalysis written by Yu S. Matros and published by VSP. This book was released on 1990-12 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades the investigation methods of unsteady state catalytic processes have been widely developed by the response-technique methods. From this research emerged the realization that under unsteady state conditions and, especially under artificially created ones, it is possible to increase the productivity or selectivity of a catalyst or a catalytical process as a whole. The scientific literature in this field is mostly theoretical and aims at structuring and analysing mathematical models of unsteady state catalytical processes. In this book the theoretical and applied aspects of an efficiency of artificially created unsteady conditions in catalysis are discussed. It contains the lectures from researchers from all over the world that were held during the International Conference ''Unsteady State Processes in Catalysis'', 5--8 June 1990, Novosibirsk (USSR). Topics include: -- The problems of dynamics of a catalyst surface -- Kinetic models of unsteady processes -- Dynamics of chemical reactors -- Artificially created unsteady processes in a catalytic reactor.

Download or read book Investigation of a Full scale Cascade type Thrust Reverser written by Robert C. Kohl and published by . This book was released on 1957 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: A double set of turning vanes was carried inside the jet tailpipe. To produce reverse thrust, the tailpipe opens into two side sections and the turning vanes move outward to form a V-shaped cascade, which deflects the exhaust-gas flow. Forward and reverse net thrust were measured over a range of engine speeds with the airplane stationary. Taxi tests were made to determine the comparative stopping distances using wheel braking and reverse thrust separately, and a combination of both. The effect of turning-vane spacing on thrust-reverser performance was determined by scale-model tests using unheated air.

Download or read book Applied Hydrogeology for Scientists and Engineers written by Zekai Sen and published by CRC Press. This book was released on 2017-12-14 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to properly plan, design, and operate groundwater resources projects, it is necessary to measure - over time or distance - pertinent groundwater variables such as drawdown and discharge in the field. Applied Hydrogeology for Scientists and Engineers shows how to assess and interpret these data by subsurface geological setup and processing. The book helps readers estimate relevant groundwater parameters such as storativity, transmissivity, and leakage coefficient. The text addresses many interrelated disciplines such as geology, hydrology, hydrogeology, engineering, petroleum geology, and water engineering. Traditional and current models for application are presented. One of the unique features of the book is the inclusion of new and previously unpublished ideas, concepts, techniques, approaches, and procedures developed by the author. Among these are hydrogeophysical concepts, slope matching techniques, volumetric approach solution for complicated groundwater flows, non-Darcian flow law applications, aquifer sample functions, dimensionless-type straight line methods, non-linear flow-type curves, discharge calculations from early time-drawdown data, storage coefficient estimation procedure for quasi-steady state flow, and much more. The pitfalls in aquifer test analysis are also detailed. Fractured medium flow adds yet another dimension to the book. Each method is supplemented by actual field data applications from worldwide case studies. Applied Hydrogeology for Scientists and Engineers covers the topics of groundwater reservoirs, the evaluation of aquifer parameters, aquifer and flow properties, flow properties and bore hole tests, aquifer tests in porous and fractured media, well hydraulics, groundwater flow and aquifer tests, and field measurements and their interpretations. This new reference also works well as a post-graduate textbook on the subject. Applied Hydrogeology for Scientists and Engineers expands the reader's knowledge by providing valuable information not found in any other publication.

Download or read book Unit Operations in Environmental Engineering written by Louis Theodore and published by John Wiley & Sons. This book was released on 2017-08-29 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents the principles of unit operations as well as the application of these principles to real-world problems. The authors have written a practical introductory text exploring the theory and applications of unit operations for environmental engineers that is a comprehensive update to Linvil Rich's 1961 classic work, "Unit Operations in Sanitary Engineering". The book is designed to serve as a training tool for those individuals pursuing degrees that include courses on unit operations. Although the literature is inundated with publications in this area emphasizing theory and theoretical derivations, the goal of this book is to present the subject from a strictly pragmatic introductory point-of-view, particularly for those individuals involved with environmental engineering. This book is concerned with unit operations, fluid flow, heat transfer, and mass transfer. Unit operations, by definition, are physical processes although there are some that include chemical and biological reactions. The unit operations approach allows both the practicing engineer and student to compartmentalize the various operations that constitute a process, and emphasizes introductory engineering principles so that the reader can then satisfactorily predict the performance of the various unit operations equipment. "This is a definitive work on Unit Operations, one of the most important subjects in environmental engineering today. It is an excellent reference, well written, easily read and comprehensive. I believe the book will serve well those working in engineering disciplines including those beyond just environmental and chemical engineering. Bottom-line: A must for any technical library". —Kenneth J. Skipka, CCM
