🔍 Key Concepts

• Gas turbine thermodynamic cycles (open, closed, semi-closed, semi-open) • The function of a regenerator in a gas turbine • What happens to exhaust gas and fresh air in each type of cycle

💭 Think About

• Think about whether the working fluid (gas/air) is exhausted to the atmosphere or kept within the system and recirculated. • Ask yourself: In which cycle type is heat from the exhaust used to preheat the compressed air before combustion, while still discharging some or all gas to the atmosphere? • Consider how a regenerator changes efficiency but does not by itself fully close the cycle like a steam Rankine cycle.

✅ Before You Answer

• Verify which cycle(s) discharge to atmosphere after expansion in the turbine. • Check which cycle definition involves recirculation of some exhaust gas back into the compressor section. • Confirm that the presence of a regenerator alone does not automatically mean a fully closed cycle.
