We consider an autonomous heat engine in simultaneous contact with a hot and a cold reservoir and describe it within a linear irreversible framework. In a tight-coupling approximation, the rate of entropy generation is effectively written in terms of a single thermal flux that is a homogeneous function of the hot and cold fluxes. The specific algebraic forms of the effective flux are deduced for scenarios containing internal and external irreversibilities for the typical example of a thermoelectric generator.
我们考虑一个同时与热库和冷库接触的自主热机，并在一个线性不可逆框架内对其进行描述。在紧密耦合近似中，熵产生率可以有效地用一个单一热通量来表示，该热通量是热通量和冷通量的齐次函数。针对热电发电机的典型例子，推导了包含内部和外部不可逆性的情况下有效通量的具体代数形式。
