Stirling and Ericsson Cycles:
- The ideal Otto and Diesel cycles are internally reversible, but not totally reversible.
- Hence their efficiencies will always be less than that of Carnot efficiency.
- For a cycle to approach a Carnot cycle, heat addition and heat rejection must take place isothermally.
- Stirling and Ericsson cycles comprise of isothermal heat addition and heat rejection.
- Both these cycles also have a regeneration process.
- Regeneration, a process during which heat is transferred to a thermal energy storage device (called a regenerator) during one part of the cycle and is transferred back to the working fluid during another part of the cycle.
