1The AirStandard AssumptionsThe working fluid is air and it behaves as an ideal gasThe cycle is modeled as a closed cyclewith the air cooled inthe chiller heat exchanger and recirculated to the compressorThe combustion chamber is replaced by combustion heatexchangerAll processes are internally reversibleThe AirStandard AssumptionsThe first analysis of most gas power cycles begins with theairstandard assumptionsFirst we assume that the working fluid is air and that at allpoints within the system it behaves as an ideal gasNext we approximate the open cycle as a closed cycle We mustadd heat exchanger 2 in order to cool the turbine effluent andcomplete the cycleThe presence of fuel and combustion products like carbondioxide and water in the working fluid can greatly complicate theanalysis of the cycleSo to avoid these complications in our basic analysis we willmodel the See Answer
