Maharashtra State Board: Class 11
Definition: Sterling Cycle
A thermodynamic cycle known for its high efficiency, consisting of four processes — isothermal expansion, isochoric heat removal, isothermal compression, and isochoric heat addition — is called the Sterling cycle.
Maharashtra State Board: Class 11
Key Points: Sterling Cycle
- The Sterling cycle uses regeneration (processes 2→3 and 4→1), which makes it highly efficient.
- QH = heat absorbed during isothermal expansion (at hot end)
- QC = heat rejected during isothermal compression (at cold end)
- No formulas are given in the provided content beyond the process descriptions.
