WebMay 3, 2024 · Stirling cycle is a thermodynamic cycle upon which a Stirling Engine works. Stirling engine is a closed cycle regenerative heat engine.It works on either air or any other gas. Stirling cycle is invented by Robert Stirling with help from his brother (in 1816). Webthe two-phase (saturated) regions where two phases can exist together in thermodynamic equilibrium: liquid-vapor, solid-liquid, or solid- vapor. Within these two-phase regions, pressure and temperature are not independent; if one changes, the other must change. Therefore, if pressure and temperature for a two-phase mixture are specified, the
