Modeling Engine Spray and Combustion Processes by Gunnar Stiesch Pdf

The utilization of mathematical models to numerically describe the performance of internal combustion engines is of great significance in the development of new and improved engines. Today, such simulation models can already be viewed as standard tools, and their importance is likely to increase further as available com puter power is expected to increase and the predictive quality of the models is constantly enhanced. This book describes and discusses the most widely used mathematical models for in-cylinder spray and combustion processes, which are the most important subprocesses affecting engine fuel consumption and pollutant emissions. The relevant thermodynamic, fluid dynamic and chemical principles are summarized, and then the application of these principles to the in-cylinder processes is ex plained. Different modeling approaches for the each subprocesses are compared and discussed with respect to the governing model assumptions and simplifica tions. Conclusions are drawn as to which model approach is appropriate for a specific type of problem in the development process of an engine. Hence, this book may serve both as a graduate level textbook for combustion engineering stu dents and as a reference for professionals employed in the field of combustion en gine modeling. The research necessary for this book was carried out during my employment as a postdoctoral scientist at the Institute of Technical Combustion (ITV) at the Uni versity of Hannover, Germany and at the Engine Research Center (ERC) at the University of Wisconsin-Madison, USA.

Advances in Chemical Propulsion by Gabriel D. Roy Pdf

Complex, vast, and multidisciplinary, chemical propulsion has been the subject of extensive investigation over the past few decades. Under the leadership of Gabriel Roy, this has been particularly true at the Office of Naval Research (ONR), where his team has focused on the three primary goals of combustion research: improving the efficiency, increasing the range and speed, and reducing the emissions and signatures of combustion systems. Advances in Chemical Propulsion: Science to Technology reports on the progress achieved by the outstanding team of scientists and engineers participating in the ONR Propulsion Program. Its chapters, each written by the scientists who performed the research, cover all aspects of the combustion process, from chemical synthesis to reaction pathways of the fuel, from combustor performance to the reduction of emissions, from the sooting problem to thrust vectoring, and from diagnostics to control. They discuss the relevant issues, describe the approach used and the results obtained, and show how the findings can be extended to practical applications. Richly illustrated and carefully edited for clarity, uniformity, and readability, Advances in Chemical Propulsion offers a comprehensive survey of the field, from pre- to post-combustion. It suggests directions for new research efforts and reflects the state-of-the-art technologies and issues that have a direct impact on combustion systems, both present and future.

Combustion Chambers for Jet Propulsion Engines by V. S. Zuyev,L. S. Skubachevskii Pdf

Combustion Chambers for Jet Propulsion Engines focuses on the design of combustion chambers for turbo-jet and ramjet engines, including reheat systems. This compilation, which is a training manual for the combustion chamber course held in the Moscow Aeronautical Institute, provides a general presentation of the basic elements of the process of operation, characteristics, and design of combustion chambers. This manual is divided into two parts. Part One discusses the elements of chemical kinetics and the theory of combustion of a homogeneous mixture in gas streams. The second part is devoted to the thermodynamics of the combustion chamber; aerodynamic and thermal losses; construction of the combustion chamber; and description of the operating process. The problem concerning the effect of losses in combustion chambers on the characteristics of jet propulsion engines is also elaborated in this text. This publication is valuable to aeronautical and combustion engineering students.

Internal Combustion Engines by Colin R. Ferguson,Allan T. Kirkpatrick Pdf

Since the publication of the Second Edition in 2001, there have been considerable advances and developments in the field of internal combustion engines. These include the increased importance of biofuels, new internal combustion processes, more stringent emissions requirements and characterization, and more detailed engine performance modeling, instrumentation, and control. There have also been changes in the instructional methodologies used in the applied thermal sciences that require inclusion in a new edition. These methodologies suggest that an increased focus on applications, examples, problem-based learning, and computation will have a positive effect on learning of the material, both at the novice student, and practicing engineer level. This Third Edition mirrors its predecessor with additional tables, illustrations, photographs, examples, and problems/solutions. All of the software is ‘open source’, so that readers can see how the computations are performed. In addition to additional java applets, there is companion Matlab code, which has become a default computational tool in most mechanical engineering programs.

Mixture Formation in Internal Combustion Engines by Carsten Baumgarten Pdf

A systematic control of mixture formation with modern high-pressure injection systems enables us to achieve considerable improvements of the combustion pr- ess in terms of reduced fuel consumption and engine-out raw emissions. However, because of the growing number of free parameters due to more flexible injection systems, variable valve trains, the application of different combustion concepts within different regions of the engine map, etc., the prediction of spray and m- ture formation becomes increasingly complex. For this reason, the optimization of the in-cylinder processes using 3D computational fluid dynamics (CFD) becomes increasingly important. In these CFD codes, the detailed modeling of spray and mixture formation is a prerequisite for the correct calculation of the subsequent processes like ignition, combustion and formation of emissions. Although such simulation tools can be viewed as standard tools today, the predictive quality of the sub-models is c- stantly enhanced by a more accurate and detailed modeling of the relevant pr- esses, and by the inclusion of new important mechanisms and effects that come along with the development of new injection systems and have not been cons- ered so far. In this book the most widely used mathematical models for the simulation of spray and mixture formation in 3D CFD calculations are described and discussed. In order to give the reader an introduction into the complex processes, the book starts with a description of the fundamental mechanisms and categories of fuel - jection, spray break-up, and mixture formation in internal combustion engines.

Simulating Combustion by Günter P. Merker,Christian Schwarz,Gunnar Stiesch,Frank Otto Pdf

The numerical simulation of combustion processes in internal combustion engines, including also the formation of pollutants, has become increasingly important in the recent years, and today the simulation of those processes has already become an indispensable tool when - veloping new combustion concepts. While pure thermodynamic models are well-established tools that are in use for the simulation of the transient behavior of complex systems for a long time, the phenomenological models have become more important in the recent years and have also been implemented in these simulation programs. In contrast to this, the thr- dimensional simulation of in-cylinder combustion, i. e. the detailed, integrated and continuous simulation of the process chain injection, mixture formation, ignition, heat release due to combustion and formation of pollutants, has been significantly improved, but there is still a number of challenging problems to solve, regarding for example the exact description of s- processes like the structure of turbulence during combustion as well as the appropriate choice of the numerical grid. While chapter 2 includes a short introduction of functionality and operating modes of internal combustion engines, the basics of kinetic reactions are presented in chapter 3. In chapter 4 the physical and chemical processes taking place in the combustion chamber are described. Ch- ter 5 is about phenomenological multi-zone models, and in chapter 6 the formation of poll- ants is described.
