Abstract :The scope of this work is twofold: first, to perfect the exergy approach to the design and optimization of aerospace propulsion systems; second, to develop a modular simulation tool in order to analyze potentialities and limits of different configurations of a scramjet engine. The vehicle is considered a “flying control volume” and is treated as a Large Complex Energy System insert ignore into journalissuearticles values(“LCES”); to which systems balances insert ignore into journalissuearticles values(mass, energy, exergy); are applied to calculate the relevant losses for each one of its elementary devices. An energy and exergy analysis of a hydrogen-fueled scramjet is presented and discussed as a first application of the procedure that shall be extended to the analysis of different scramjet-configurations, fueled by H2-alternative fuels: an exergy-based performance comparison can consequently complement an energy and thrust-based analysis. All calculations have been performed with CAMEL ® , an “in-house” modular process simulator code for energy conversion processes.
