Ciclos con Turbinas de Gas

This book describes the thermodynamics of gas turbine cycles (although it does touch briefly on the economics of electrical power generation). The strictures of classical thermodynamics require that “cycle” is used only for a heat engine operating in closed form, but the word has come to cover “open circuit” gas turbine plants, receiving “heat” supplied through burning fuel, and eventually discharging the products to the atmosphere (including crucially the carbon dioxide produced in combustion). The search for high gas turbine efficiency has produced many suggestions for variations on the simple “open circuit” plant suggested by Barber, but more recently work has been directed towards gas turbines which produce less COz, or at least plants from which the carbon dioxide can be disposed of, subsequent to sequestration.

The book contains brief descriptions of fundamental and combustion processes, followed by an extensive survey of the combustion research technology. It also includes mathematical modeling of the processes covering mainly premixed and diffusion flames, where many chemical and physical processes compete in complex ways, for both laminar and turbulent flows. This provides a unique bridge between combustion fundamentals and combustion technology, which should make the book a valuable technical reference for many engineers and scientists. Moreover, the book gives the reader sufficient background of basic engineering sciences such as chemistry, thermodynamics, heat transfer and fluid mechanics. The mentioned research and mathematical models fit between small-scale laboratory burner flames, and large-scale industrial boilers, furnaces and combustion chambers. The materials of this book have been collected from previous relevant research and some selected papers of the authors and co-workers, which have been presented mainly in different refereed journals, international conferences and symposiums.
