An open-cycle or closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, etc.) for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source. Such recirculating turbines follow the Brayton cycle.
Gas turbines operate on the Brayton cycle/Joule cycle. The Joule cycle consists of four internally reversible processes:
- Isentropic compression (in a compressor)
- Constant-pressure heat addition
- Isentropic expansion (in a turbine)
- Constant-pressure heat rejection
Otto cycle: It is the standard air cycle used in the spark ignition (SI) engines or petrol engines.
The Carnot cycle can be thought of as the most efficient heat engine cycle.
Stirling engine is used in a mechanical propulsion system and electrical generation systems.
