Generalized and additive Clausius entropy

Year: 2026

Type: preprint

Abstract: A generalized Clausius inequality is derived within the macroscopic, nonstatistical, and phenomenological framework of classical thermodynamics. The inequality should be valid for both quasistatic and nonquasistatic cycle processes. It will share some similarities with the integral entropy imbalance inequality of continuum thermodynamics. The generalized Clausius inequality leads to a generalized Clausius entropy. Moreover, it is shown that the generalized entropy is additive, at least for a not too large composite of disjoint, adjacent thermodynamic systems existing contemporaneously, and without relative speed.
