Abstract:

Enormous strides have been made on gas turbine cycles in recent years. In addition, different practices of studies are being carried on in order to increase the cycle efficiency. In this study, CO 2 (carbon dioxide or R744) and thermo dynamic analysis of supercritical Brayton cycles having air flow fluidity have separately been studied. Cyclical equipment working in supercritical conditions and its energy exergy performance at different cycles of parameters, and turbine inlet temperature and the effects of pressure, and compressor pressure ratio, and compressor efficiency on performance are surveyed examined. Analyze work is sorted out through a computer software (Engineering Equation Solver-EES).Supercritical CO 2 (S-CO 2) turbine effects on efficiency increase in power conversions are evaluated and its future in the energy sector is discussed.
