Thermodynamic analysis of mirror gas turbine cycle

An interesting configuration of the gas turbine is the mirror gas turbine cycle. There have been several developments in the thermodynamic analysis of various combined or co-generation cycle schemes, with more advanced heat recovery capabilities. One of such novel cycles is the mirror cycle, a conceptual combination of Brayton and inverted Brayton cycles with heat sink by intercooling. In this analysis, an air standard cycle is assumed for the gas turbine. Analysis about the specific net-power and the efficiency of the mirror gas turbine as a function of maximum temperature ratio, compressor pressure ratio, and turbine overall expansion ratio of the cycle are performed. The obtained results provide significant guidance to the evaluation and improvement of the mirror gas turbine.
