Heat Transfer in Energy Conversion Systems by Alessandro Mauro,Nicola Massarotti,Laura Vanoli Pdf

In recent years, the scientific community’s interest towards efficient energy conversion systems has significantly increased. One of the reasons is certainly related to the change in the temperature of the planet, which appears to have increased by 0.76 °C with respect to pre-industrial levels, according to the Intergovernmental Panel on Climate Change (IPCC), and this trend has not yet been stopped. The European Union considers it vital to prevent global warming from exceeding 2 °C with respect to pre-industrial levels, since this phenomenon has been proven to result in irreversible and potentially catastrophic changes. These climate changes are mainly caused by the emissions of greenhouse gasses related to human activities, and can be drastically reduced by employing energy systems, for both heating and cooling of buildings and for power production, characterized by high efficiency levels and/or based on renewable energy sources. This Special Issue, published in the journal Energies, includes 12 contributions from across the world, including a wide range of applications, such as HT-PEMFC, district heating systems, a thermoelectric generator for industrial waste, artificial ground freezing, nanofluids, and others.

Thermodynamics and Energy Conversion by Henning Struchtrup Pdf

This textbook gives a thorough treatment of engineering thermodynamics with applications to classical and modern energy conversion devices. Some emphasis lies on the description of irreversible processes, such as friction, heat transfer and mixing and the evaluation of the related work losses. Better use of resources requires high efficiencies therefore the reduction of irreversible losses should be seen as one of the main goals of a thermal engineer. This book provides the necessary tools. Topics include: car and aircraft engines, including Otto, Diesel and Atkinson cycles, by-pass turbofan engines, ramjet and scramjet; steam and gas power plants, including advanced regenerative systems, solar tower and compressed air energy storage; mixing and separation, including reverse osmosis, osmotic power plants and carbon sequestration; phase equilibrium and chemical equilibrium, distillation, chemical reactors, combustion processes and fuel cells; the microscopic definition of entropy. The book includes about 300 end-of-chapter problems for homework assignments and exams. The material presented suffices for two or three full-term courses on thermodynamics and energy conversion.

Principles of Heat Transfer in Porous Media by M. Kaviany Pdf

Although the empirical treatment of fluid flow and heat transfer in porous media is over a century old, only in the last three decades has the transport in these heterogeneous systems been addressed in detail. So far, single-phase flows in porous media have been treated or at least formulated satisfactorily, while the subject of two-phase flow and the related heat-transfer in porous media is still in its infancy. This book identifies the principles of transport in porous media and compares the avalaible predictions based on theoretical treatments of various transport mechanisms with the existing experimental results. The theoretical treatment is based on the volume-averaging of the momentum and energy equations with the closure conditions necessary for obtaining solutions. While emphasizing a basic understanding of heat transfer in porous media, this book does not ignore the need for predictive tools; whenever a rigorous theoretical treatment of a phenomena is not avaliable, semi-empirical and empirical treatments are given.

The Thermoeconomics of Energy Conversions by Yehia M. El-Sayed Pdf

The Thermoeconomics of Energy Conversions presents the developed methodologies that reveal the cost effectiveness of energy-resource-saving ideas design. This book discusses the theory of thermoeconomics. Organized into nine chapters, this book begins with an overview of the foundation of the design analysis of systems that use or produce useful forms of energy. This text then examines the rational basis for costing energy conversion devices for the purpose of optimal system design. Other chapters consider the enhancement of system optimization. This book discusses as well the significance of the design models of energy conversion devices as rich resources for predicting both their costs and overall performance of their system. The final chapter deals with the software of the accompanying compact disc. This book is a valuable resource for engineers and scientists who are involved in the development of efficient energy conversion systems. Students, system designers, and device designers will also find this book useful.

Preliminary Weight Estimates for Advanced Dynamic Energy Conversion Systems by George D. Huffman Pdf

An assessment of working fluids for use in a high-temperature dynamic power conversion system is presented. The method of comparison of the various fluids consists of a preliminary design of the major system components. The results are presented as conversion system weights for the considered fluids, potassium, sodium, lithium, bismuth, and lead, at various values of turbine inlet temperatures. On the basis of the generated data, it has been concluded that only potassium and sodium are practical for use as a working fluid in the temperature range of consideration, 2000 to 4000 R. It is further concluded that potassium and sodium at turbine inlet temperatures from 2800 to 3200 R offer systems of sufficiently low weight to warrant further and more detailed investigations.
