Pitfalls of Exergy Analysis [PDF]
Journal of Non-Equilibrium Thermodynamics, 2017 Abstract The well-known Gouy–Stodola theorem states that a device produces maximum useful power when working reversibly, that is with no entropy production inside the device. This statement then leads to a method of thermodynamic optimization based on entropy production minimization.
