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.

Download Handbook of Hydrogen Energy Book in PDF, ePub and Kindle
Can hydrogen and electricity supply all of the world’s energy needs? Handbook of Hydrogen Energy thoroughly explores the notion of a hydrogen economy and addresses this question. The handbook considers hydrogen and electricity as a permanent energy system and provides factual information based on science. The text focuses on a large cross section of applications such as fuel cells and catalytic combustion of hydrogen. The book also includes information on inversion curves, physical and thermodynamic tables, and properties of storage materials, data on specific heats, and compressibility and temperature–entropy charts and more. Analyzes the principles of hydrogen energy production, storage, and utilization Examines electrolysis, thermolysis, photolysis, thermochemical cycles, and production from biomass and other hydrogen production methods Covers all modes of hydrogen storage: gaseous, liquid, slush, and metal hydride storage Handbook of Hydrogen Energy serves as a resource for graduate students, as well as a reference for energy and environmental engineers and scientists.

Download Modelling Diesel Combustion Book in PDF, ePub and Kindle
This book comprehensively discusses diesel combustion phenomena like ignition delay, fuel-air mixing, rate of heat release, and emissions of smoke, particulate and nitric oxide. It enables quantitative evaluation of these important phenomena and parameters. Most importantly, it attempts to model them with constants that are independent of engine types and hence they could be applied by the engineers and researchers for a general engine. This book emphasizes the importance of the spray at the wall in precisely describing the heat release and emissions for most of the engines on and off-road. It gives models for heat release and emissions. Every model is thoroughly validated by detailed experiments using a broad range of engines. The book describes an elegant quasi-one-dimensional model for heat release in diesel engines with single as well as multiple injections. The book describes how the two aspects, namely, fuel injection rate and the diameter of the combustion bowl in the piston, have enabled meeting advanced emission, noise, and performance standards. The book also discusses the topics of computational fluid dynamics encompassing RANS and LES models of turbulence. Given the contents, this book will be useful for students, researchers and professionals working in the area of vehicle engineering and engine technology. This book will also be a good professional book for practising engineers in the field of combustion engines and automotive engineering.

Download Smart Energy Strategies Book in PDF, ePub and Kindle
The enormous challenge of creating a longterm sustainable energy system calls for the participation of engineers, natural and social scientists. They can contribute both through their research and by helping to craft strategies that steer the future development of the system. A sustainable energy system cannot be developed by technical fixes alone; action is required on a broad front, including institutional and regulatory changes. There is an abundance of scientific evidence on which to base decisions on how to proceed. Still, research has a crucial role to play as well.Smart Energy Strategies highlights smart solutions: advances in technical and social-science energy research, particularly advances related to new information technology (e.g. control and communication); and experience with targeted applications of information technology in the supply and consumption of energy. The conference has focused on smart strategies taking into account current technical and institutional systems, with their inertia and shortcomings; future energy-related challenges: energy security; the growing energy needs of the disadvantaged; and unintended consequences of energy systems, particularly climate change but also uncontrolled money flows; smart technical, institutional, and regulatory mechanisms for meeting these challenges.
