It is becoming more and more important to manage energy resources effectively: to maximize their benefits while minimizing the negative environmental impacts. Scientist and engineers are thus faced with the problem of optimizing complex systems subject to constraints from, ecology, economics, and thermodynamics. It is chiefly to the last that the present volume is addressed. Nonequilibrium thermodynamic approaches, such as finite-time thermodynamics and Second-Law analyses, can provide realistic models and analyses that can be used to search for optimum ways to operate machines and processes. Intended for physicists, chemists, and engineers, this volume reviews the state of the art in the thermodynamics of energy conversion and transmission. Using examples from solar, thermal, mechanical, chemical, and environmental engineering, the book focuses on the use of thermodynamic criteria for optimizing energy conversion and transmission. The first set of chapters focuses on solar energy conversion; the second set discusses the transfer and conversion of chemical energy (as in internal combustion engines or distillation columns); a concluding set of chapters deals with geometric methods in thermodynamics.

The first book to provide a comprehensive treatment integrating finite-time thermodynamics and optimal control, giving an overview of important breakthroughs in the last 20 years. It presents a survey of the optimization technique, including the basics of optimal control theory, and the principal thermodynamic concepts and equations. In addition, it covers the solutions of a variety of finite-time thermodynamic problems, including coverage of their potential applications for the design of real technological processes, such as: * heat-exchange systems * mass transfer and separation processes * commodity exchange as a finite-time thermodynamic process * heat-driven mechanical processes with one or several reservoirs. This is a key resource for chemical and mechanical engineers involved in power systems and process engineering. Researchers in theoretical, physical and industrial chemistry in academia and in industry will also welcome this book for the fresh perspectives that offer new ways to design and analyze a wide variety of processes.

This study is one of the first attempts to bridge the theoretical models of variational dynamics of perfect fluids and some practical approaches worked out in chemical and mechanical engineering in the field newly called thermo-hydrodynamics. In recent years, applied mathematicians and theoretical physicists have made significant progress in formulating analytical tools to describe fluid dynamics through variational methods. These tools are much loved by theoretists, and rightly so, because they are quite powerful and beautiful theoretical tools. Chemists, physicists and engineers, however, are limited in their ability to use these tools, because presently they are applicable only to "perfect fluids" (i. e. those fluids without viscosity, heat transfer, diffusion and chemical reactions). To be useful, a model must take into account important transport and rate phenomena, which are inherent to real fluid behavior and which cannot be ignored. This monograph serves to provide the beginnings of a means by which to extend the mathematical analyses to include the basic effects of thermo-hydrodynamics. In large part a research report, this study uses variational calculus as a basic theoretical tool, without undo compromise to the integrity of the mathematical analyses, while emphasizing the conservation laws of real fluids in the context of underlying thermodynamics --reversible or irreversible. The approach of this monograph is a new generalizing approach, based on Nother's theorem and variational calculus, which leads to the energy-momentum tensor and the related conservation or balance equations in fluids.
