Lecture
This lecture covers the Stirling cycle, proposed by R. Stirling in 1816, which involves two isotherms and two isochores. The cycle's practical realization includes heating isochore, isothermal expansion, cooling isochore, and isothermal compression. The Stirling engine operates based on pressure variations in a closed fluid circuit, allowing for diverse fuel usage and alternative heat sources like solar radiation. The lecture also discusses the efficiency calculation for a perfect gas and the relationship between heat exchanges, temperatures, and efficiency in Carnot and Stirling cycles.
