Path Entropy Changes in Quasi-Static Approach    [PDF]

Jang-il Sohn

It is well known that total entropy change is composed of non-adiabatic and adiabatic entropy changes. Those are derived from time reversible processes. In this research, time reversible processes are replaced with quasi-static processes by introducing observing period {\tau} and temporarily time homogeneous Markov process. It is shown that the non-adiabatic entropy change is equivalent to entropy change in quasi-static processes. Entropy changes in quasi-static processes, transient state and steady state are discussed by modifying {\tau} . As an additional result, an easy way to calculate those entropy changes is introduced.
