The Carnot cycle is a hypothetical cycle in which the efficiency is a maximum. It was proposed by Nicolas Léonard Sadi Carnot [1]. The Carnot cycle consists of four distinct operations:
- A reversible isothermal expansion of the gas at the "hot" temperature, THot
- An isentropic reversible adiabatic expansion of the gas
- A reversible isothermal compression of the gas at the "cold" temperature, TCold
- Finally an isentropic compression of the gas
