Stirling Engine: Thermodynamic Principles

This lecture introduces dithermal machines, which alternate between two heat sources, presenting three experiments: a bird toy demonstrating the first law of thermodynamics, a vacuum engine identifying hot and cold sources, and a Stirling engine with constant gas quantity. The explanation includes the functioning of a bird toy using temperature measurements, a vacuum engine's operation with a rapid camera, and a Stirling engine's construction and operation. The Stirling cycle on a PV diagram is detailed, highlighting isothermal, isochoric, and isobaric processes, and defining terms like adiabatic and isentropic processes in thermodynamics.
