- W285224141 abstract "The present text draws attention to three interrelated topics; aero engine system simulation, evaluation of losses through exergy analysis and the search for more energy efficient power plants. The first chapter reviews the historical development of simulation tools, with anemphasis on generic programs, and discusses efficient numerical solution techniques and suitable solvers. A short discussion on multidisciplinary optimization tools is given. The chapter also briefly reviews the state of the art in terms of commercially available software for aeroengine simulation and discusses the needs and uses in industrial applications. The second chapter introduces the concept of exergy analysisand develops the necessary equations for applying the theory to evaluate losses in aero engines. The third chapter pursues future ultra efficient engines designed for an estimated 2050 technology level. Theanalysis is based on mission optimization starting with a conventional three shaft engine. The concept of exergy analysis is then used to show where in the cycle that major efficiency improvements of such an engine can be accomplished. This is followed by a discussion on a numberof cycle innovations that can target the observed losses. Optimization is used to quantify the improvement potential." @default.
