Thermodynamic Stirling Cycle and Stirling Engine - Part 1. How does Stirling cycle work? What is Stirling Cycle? How do Stirling Engines work?

Thermodynamic Stirling cycle comprises to two reversible isothermal and two reversible isochoric processes. In the initial years the Stirling engines were used frequently but were later replaced by other engines. In the recent years they have been gaining their lost ground.
