THE THERMOECONOMICS OF ENERGY CONVERSIONS

Descripción

The increasing demand for power and material products by current energy conversion technologies using fossil and nuclear fuels on one hand and the adverse impact on the environment on the other hand, did create an energy conversion crisis that is going to stay for decades to come. The increasing demand is driven by the increase of world population and a rising standard of living. The adverse impact is emissions, waste disposal, and the signs of global warming. The long-lasting energy conversion crisis is due to the absence of alternative energy resources and conversion technologies that are both friendly to the environment and economically competitive to the present ones. Until emerging or new competitive technologies become available, the cost-effective increase of the conversion efficiencies of current technologies is the only option to reduce the impact of the crisis. Directions of raising system efficiency are well established thermodynamically but not the directions of their cost effectiveness. The book surveys briefly the recently developed methodologies that reveal the cost effectiveness of sought energy-resource-saving ideas by design. The book then focuses on one methodology that became known as thermoeconomics. The theory is presented. Tutorial and application examples are given. The examples deal with both systemdesign analysis and the design analysis of energy conversion devices. A number of executable programs set the stage for the analyses and provide the results. The programs are described and samples of the source code in "BASIC" are included. All programs are available on one compact disc. The goal of the book is a set of energy analysis tools that is useful, concise and easy to understand and apply. The book is an outcome of more than a 20-year development of thermoeconomics. The book will be useful to both a system-designer and a device-designer. It will be particularly useful to students. They will be prepared to reshape the traditional energy system design during their active career into a more powerful optimal-design methodology. Thermoeconomics launches an intensive analysis dose on the design concepts of energy conversion systems for the purpose of revealing opportunities of fuel and cost savings. The description of system configurations is modular, process-oriented, and is easy to expand or modify. The approach to the solution of the modeling equations of a configuration is numerical.
