2. Distribution of entropy production between sources and sinks
2.1 Endoreversibility
As a final example of a general property, we'll look at the optimal distribution of entropy production in a thermal transformation process involving several heat sources and sinks. The approach developed below is based on the notion of an endoreversible process, which we briefly introduce.
Definition: an "endoreversible process" is one in which the only irreversibilities are those linked to exchanges between the process and the outside world.
In other words, "internal" irreversibilities - those that do not involve external exchanges - are neglected. The advantage of this concept is that it allows partial optimization of the process (in terms of its exchanges with the outside...
