A review on exergy analysis of aerospace power systems

摘要

Exergy, an integration of the first and second laws of thermodynamics, enriches the traditional analysis method based on energy conservation. It can effectively reveal the causes of the irreversibilities and inefficiencies of the thermodynamic processes, which provides a convenient approach for engineers to design and optimize the components and systems. This paper firstly introduces the development history of exergy and the fundamental mathematics behind exergy analysis in general. Next, the application status of exergy analysis method in turbojet/turbofan engines, scramjet engine, aircraft system and multidisciplinary design optimization is represented in detail. At the end of this review, we put forward the practical needs for further development of exergy analysis and conclude that this method has wide application prospect in the field of aerospace power systems.
