摘要：Exergy analysis and optimization is carried out for combined regenerative Brayton and inverse Brayton cycles with regenerator after the inverse cycle. The analytical formulae of exergy efficiency of the combined cycle and exergy losses of each component are derived. The largest exergy loss location is determined. It is shown that exergy efficiency increases with the increase in the effectiveness of regenerator in the critical range of the compressor pressure ratio of the bottom cycle. Furthermore, the exergy loss of combustion chamber is the largest in the combined cycle .
