Combustion Instabilities in Gas Turbine Engines: Operational Experience, Fundamental Mechanisms, And Modeling (Progress in Astronautics and Aeronautics)

Higher operating efficiencies, fewer pollutant emissions, and low capital investment have made gas turbines a dominant technology for new power generating capacity in the U.S. and worldwide. This book offers gas turbine users and manufacturers a valuable resource to help them sort through issues associated with combustion instabilities. In the last ten years, substantial efforts have been made in the industrial, governmental, and academic communities to understand the unique issues associated with combustion instabilities in low-emission gas turbines. The objective of this book is to compile these results into a series of chapters that address the various facets of the problem. The Case Studies section speaks to specific manufacturer and user experiences with combustion instabilities in the development stage and in fielded turbine engines. The book then goes on to examine The Fundamental Mechanisms, The Combustor Modeling, and Control Approaches. - Data and information appearing in this book are for informational purposes only.

Lieuwen (aerospace engineering, Georgia Institute of Technology) and Yang (mechanical engineering, The Pennsylvania State University) offer gas turbine users and manufacturers a resource on combustion instabilities in low-emission gas turbines, focusing on combustion- driven oscillations. Case studies are followed by chapters on fundamental processes and mechanisms in combustion instabilities in premixed and nonpremixed combustors. A section on models and diagnostics describes analytical and computational approaches for modeling the acoustic characteristics of combustor geometries. Final chapters cover combustion instability and control. Annotation ©2005 Book News, Inc., Portland, OR

Higher operating efficiencies, fewer pollutant emissions, and low capital investment have made gas turbines a dominant technology for a new power generating capacity in the US and worldwide. This book offers gas turbine users and manufacturers a resource to help them sort through issues associated with combustion instabilities. COMBUSTION instabilities are characterized by large-amplitude oscillations of one or more natural acoustic modes of the combustor.
