    Abstract

    Gas-turbine cycles with high fogging compression could offer enhanced efficiency and lowcomplexity. Whereas compression power and heat rates decrease when small amounts of water (upto 2% of air flow by mass) are injected at the machine inlet, increased injection amounts could allow implementation of regeneration, further decreasing the heat rate. In this study, an exergy analysis is carried out for two high-fogging cycles. The theoretical projections show that high-injection improves the efficiency from 47% at a pressure ratio of 6-55.5% at a pressure ratio of 22.
