Abstract

The study presented in this article examined the thermodynamic performance of a proposed system constructed from Brayton, inverse Brayton, and steam Rankine cycles.The theoretical examination was performed by varying the Brayton cycle pressure ration for different ratios of the inverse Brayton power turbine mass flow to the gas generator mass flow.The results indicated that for the three values of mass flow ration examined, better performance could be achieved when the proposed system is operated at high Braton cycle pressure ratio (high maximum system temperature and the mass flow equal to 0.25, the proposed system achieved the highest value of Brayton cycle pressure ratio and attained a maximum thermal efficiency of 57.7 per cent. © IMechE 2006.
