Book Synopsis Modeling Engine Spray and Combustion Processes by : Gunnar Stiesch
Download or read book Modeling Engine Spray and Combustion Processes written by Gunnar Stiesch and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Computational Optimization of Internal Combustion Engines written by Yu Shi and published by Springer Science & Business Media. This book was released on 2011-06-22 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Optimization of Internal Combustion Engines presents the state of the art of computational models and optimization methods for internal combustion engine development using multi-dimensional computational fluid dynamics (CFD) tools and genetic algorithms. Strategies to reduce computational cost and mesh dependency are discussed, as well as regression analysis methods. Several case studies are presented in a section devoted to applications, including assessments of: spark-ignition engines, dual-fuel engines, heavy duty and light duty diesel engines. Through regression analysis, optimization results are used to explain complex interactions between engine design parameters, such as nozzle design, injection timing, swirl, exhaust gas recirculation, bore size, and piston bowl shape. Computational Optimization of Internal Combustion Engines demonstrates that the current multi-dimensional CFD tools are mature enough for practical development of internal combustion engines. It is written for researchers and designers in mechanical engineering and the automotive industry.

Book Synopsis Modeling and Control of Engines and Drivelines by : Lars Eriksson
Download or read book Modeling and Control of Engines and Drivelines written by Lars Eriksson and published by John Wiley & Sons. This book was released on 2014-04-07 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control systems have come to play an important role in the performance of modern vehicles with regards to meeting goals on low emissions and low fuel consumption. To achieve these goals, modeling, simulation, and analysis have become standard tools for the development of control systems in the automotive industry. Modeling and Control of Engines and Drivelines provides an up-to-date treatment of the topic from a clear perspective of systems engineering and control systems, which are at the core of vehicle design. This book has three main goals. The first is to provide a thorough understanding of component models as building blocks. It has therefore been important to provide measurements from real processes, to explain the underlying physics, to describe the modeling considerations, and to validate the resulting models experimentally. Second, the authors show how the models are used in the current design of control and diagnosis systems. These system designs are never used in isolation, so the third goal is to provide a complete setting for system integration and evaluation, including complete vehicle models together with actual requirements and driving cycle analysis. Key features: Covers signals, systems, and control in modern vehicles Covers the basic dynamics of internal combustion engines and drivelines Provides a set of standard models and includes examples and case studies Covers turbo- and super-charging, and automotive dependability and diagnosis Accompanied by a web site hosting example models and problems and solutions Modeling and Control of Engines and Drivelines is a comprehensive reference for graduate students and the authors’ close collaboration with the automotive industry ensures that the knowledge and skills that practicing engineers need when analysing and developing new powertrain systems are also covered.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : An efficient spray injection results in better vaporization and air-fuel mixing, leading to combustion stability and reduction of emissions in the internal combustion (IC) engines. The impingement of liquid fuels on chamber wall or piston surface in IC engines is a common phenomenon and fuel film formed in the spray-piston or cylinder wall impingement plays a critical role in engine performance and emissions. Therefore, the study of the spray impingement on the chamber wall or position surface is necessary. To understand the spray-wall interaction, a single droplet impingement on a solid surface with different conditions was first examined. The droplet-wall interaction outcomes, in particular focusing on the splashing criteria, were inspected and post-impingement characterizations including spreading factor, height ratio, contact line velocity, and dynamic contact angle was further analyzed based on the experimental data. The non-evaporation volume of fluid (VOF) model based on Eulerian approach was used to characterize single droplet impinging on the wall and provide a better understanding of the dynamic impact process. In addition, the study of droplet-to-droplet collision and multi-droplet impingement on a solid surface are performed, which is essential to aid in the spray-wall impingement investigation. As well, due to the evaporation drawing more attention during the engine combustion process, an evaporation VOF sub-model was developed and applied to multi-droplet impingement on a hot surface to qualitatively and quantitatively analyze the vaporizing process as droplets impacting onto the hot surface. After that, the non-vaporizing and vaporizing spray characteristics of spray-wall impingement at various operating conditions relevant to diesel engines were undertaken, with spray characterized using schlieren and Mie scattering diagnostics, as well as Refractive Index Matching (RIM) technique. Free and impinged spray structures and deposited wall-film formation and evaporation were qualitatively analyzed, spray properties and wall-film properties were quantified, and surface temperature and heat flux were measured. An Eulerian-Lagrangian modeling approach was employed to characterize the spray-wall interactions by means of a Reynolds-Averaged Navier-Stokes (RANS) formulation. The local spray characteristics in the vicinity of the wall and the local spray morphology near the impingement location were studied. Furthermore, multiple spray-to-spray collision derived from droplet-to-droplet collision, considering as one of the advanced injection strategies to enhance the engine performance, was studied at various gasoline engine conditions to explore the effect of colliding spray on spray related phenomena like atomization, vaporization, and mixing. Spray characteristics were obtained by the schlieren diagnostics and the experimental validated Computational Fluid Dynamic (CFD) simulations were based on Eulerian-Lagrangian approach to understand the mechanism behind the collisions of sprays and characterize the different types of multiple spray-to-spray collision. In summary, on the strength of the study of droplet-wall impingement and droplet-to-droplet collision at non-evaporation and evaporation states, the main objective of this dissertation is to enhance the understanding of spray-wall impingement and multiple spray-to-spray collision under diesel or gasoline engine conditions from both experiments and CFD simulations, therefore providing feedbacks to the ultimate task in future development and application of a more reliable and effective fuel injection system.

Available in PDF, EPUB and Kindle. Book excerpt: The report consists of two parts. Part One is concerned principally with the physics of the interaction of droplets or solid particles with a gas stream in the presence of heat and mass exchange and with the influence of these factors on the characteristics of the engine. The problems of liquid injection (the basic parameters of the fuel-supply system and methods of measurement) are considered, dimensionless relationships are cited for spray spectra in a supersonic stream, and ranges and vaporizabilities in fuel sprays are determined. Part Two describes the process of turbulent mixing for various boundary conditions with or without evolution of heat on the basis of a consistent method of calculation; the relationships obtained can be used to calculate turbulent mixing in the cases of free jet, jet at a wall, and a jet in a nozzle.
