STUDY ON EXERGY ANALYSIS OF A COMPRESSED AIR ENGINE

ABSTRACT
In order to reduce exergy loss and optimize exergy efficiency of a compressed air engine (CAE), a theoretical exergy analysis model of the CAE is proposed and a working principle of the CAE based on a conventional IC engine is described. In addition, exergy balance equations of the working process at different stages are setup. The effects of rotational speed, supply pressure and ambient temperature are revealed in the simulation analysis, which have important influences on the exergy efficiency of the CAE. All these analyses of this paper will provide a theoretical basis for further study on optimizing design of the CAE.
