Book excerpt: The Green Challenge is an up-to-date and comprehensive account of the development of Green parties in Western Europe, and includes an account of the development since 1989 of an East European Green movement. Blending theory and empirical analysis, the book contains chapters on each of the main western European cases and on a number of other less-studied ones. These are designed to demonstrate the shifting balance of party-political competition the factor the authors believe most strongly influences the fortunes of the Greens. The editors also integrate a valuable analysis of the environmentally-degraded Czech Republic, where the Green parties' lack of electoral success has puzzled many observers.

Download or read book Debating the Democratic Legitimacy of the European Union written by Beate Kohler-Koch and published by Rowman & Littlefield Publishers. This book was released on 2007-04-18 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discussion about a constitution for the European Union and its rejection by referendum in two of the EU founding member states has once again spurred public and scholarly interest in the democratic quality and potential of the European Union. Debating the Democratic Legitimacy of the European Union brings together distinguished thinkers from law, political science, sociology, and political philosophy to explore the potential for democratically legitimate governance in the European Union. Drawing on different theoretical perspectives and strands from democratic theory, this volume is the first of its kind to overcome the present state of fragmentation in the debate about the conditions and possible remedies for what is often called the "democratic deficit" of the European Union. Among the pressing questions addressed by the contributors are: What future is there for parliamentary democracy in the European Union? Can we observe the evolution of a European public sphere and civil society? Can participatory democracy or deliberative democracy pave the road for a democratically legitimate European Union? Conversations about democracy have engaged the public in a new way since the beginning of the Iraq war, and this volume is the best resource for students and readers who are interested in democracy in the European Union.

This book was released on 1999 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an increasingly challenging commercial environment, and the need imposed by safety principles to reduce both fuel consumption and pollutant emissions, the development of new engines can now benefit from the advances of computational fluid dynamics. Engine CFD is a most challenging simulation problem. This is caused by the spread of time and space scales, the excursion amplitude of most parameters, the high quasi-cyclic unstationarity of engine flows, the importance of minor geometry details, the number of physical and chemical processes including turbulent combustion and multi-phase flows to model. However, engine CFD has now reached a state where it has become a widely used tool, not only for engine understanding, but also increasingly for engine design. Undoubtedly, laser diagnostics in optical access engines have also brought significant help.Contents: 1. State of the art of multi-dimensional modeling of engine reacting flows. 2. Simulation of the intake and compression strokes of a motored 4-valve SI engine with a finite element code. 3. A parallel, unstructured-mesh methodology for device-scale combustion calculations. 4. Large-eddy simulation of in-cylinder flows. 5. Simulation of engine internal flows using digital physics. 6. Automatic block decomposition of parametrically changing volumes. 7.

Available in PDF, EPUB and Kindle. Book excerpt: Phenomenology of Diesel Combustion and Modeling Diesel is the most efficient combustion engine today and it plays an important role in transport of goods and passengers on land and on high seas. The emissions must be controlled as stipulated by the society without sacrificing the legendary fuel economy of the diesel engines. These important drivers caused innovations in diesel engineering like re-entrant combustion chambers in the piston, lower swirl support and high pressure injection, in turn reducing the ignition delay and hence the nitric oxides. The limits on emissions are being continually reduced. The- fore, the required accuracy of the models to predict the emissions and efficiency of the engines is high. The phenomenological combustion models based on physical and chemical description of the processes in the engine are practical to describe diesel engine combustion and to carry out parametric studies. This is because the injection process, which can be relatively well predicted, has the dominant effect on mixture formation and subsequent course of combustion. The need for improving these models by incorporating new developments in engine designs is explained in Chapter 2. With “model based control programs” used in the Electronic Control Units of the engines, phenomenological models are assuming more importance now because the detailed CFD based models are too slow to be handled by the Electronic Control Units. Experimental work is necessary to develop the basic understanding of the pr- esses.

This book was released on 2012 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to fulfil future emissions legislations, new combustion systems are to be investigated. One way of improving exhaust emissions is the application of multiple injection strategies and conventional or partially premixed combustion conditions to a Diesel engine. The application of numerical techniques as CFD supports and improves the quality of engine developments. Unfortunately, current spray and combustion models are not accurate enough to simulate multiple injection systems, being in this way a topic of research. The goal of this study was the development of a novel simulation method for the investigation of Diesel engines operated with multiple injection strategies and different combustion modes. The first part of this work focused in improving the spray modelling. The inform ation of 3D CFD simulations of the injector nozzle was introduced in the spray simulation as boundary conditions developing coupling subroutines for this issue. The atomisation modelling was also improved using validated presumed droplet size distributions. Moreover, to avoid the simulation of the injector nozzle for every investigated operating point, a novel interpolating tool was developed in order to create spray boundary conditions based on few 3D CFD simulations of the nozzle under certain initial and boundary conditions. The second part of this thesis dealt with the combustion modelling of Diesel engines. For this issue, a laminar flamelet approach called Representative Interactive Flamelet model (RIF) was selected and implemented. Afterwards, an extended combustion model based on RIF was developed in order to take into account multiple injection strategies. Finally, this new model was validated with a wide range of operating points: applying multiple injection strategies under conventional and partially premixed combustion conditions.
