Information
This example package illustrates, step by step, several configurations of the Joule cycle that can be modeled using idealized state-change components, in particular Adiabatic and Isobaric processes.
The Joule (Brayton) cycle is a thermodynamic cycle describing the operation of gas-turbine systems. It is widely applied in jet engines and modern gas-turbine power plants due to its high power-to-weight ratio and continuous combustion process. The cycle employs a working fluid, typically air, which passes through four fundamental processes:
- Compression in a
compressor: adiabatic process with isentropic efficiency - Heat addition at elevated pressure in a combustor or heat exchanger: isobaric process
- Expansion in a
turbineto generate work: adiabatic process with isentropic efficiency - Heat rejection to the surroundings: isobaric process, artificially closing the loop through the environment
