A Thermodynamic Study of Pressure Gain Combustion in Combined Cycles

Journal of Physics: Conference Series
Abstract Gas turbines are internal combustion engines based on the Brayton-Joule cycle with four thermodynamic processes including air compression, constant pressure combustion, gas expansion and heat rejection. Actually, a relevant increase in entropy production is related to the constant pressure combustion, even in the ideal cycle, so
