所有的准静态过程都是可逆的吗?

Are all Quasi-static Processes Reversible?

Debasis Mukhopadhyay, Kamal Bhattacharyya

摘要:

一个过程,以逐步的方式进行,成为准静态时,中间步骤的数量趋于无穷大。通常,在此限制条件下,净熵产生接近于零。因此,这种情况被称为可逆的。一个最好的例子是在非等温热传递过程中,在源和汇之间引入无限数量的中温储层。我们分析的情况,并得出结论,这种准静态过程是不可逆的。事实上,由于额外的功项,没有任何非等温热传递过程是可逆的。

英文摘要:

A process, carried out in a stepwise manner, becomes quasi-static when the number of intermediate steps tends to infinity. Usually, the net entropy production approaches zero under this limiting condition. Hence, such cases are termed reversible. A favorite example is the introduction of an infinite number of intermediate-temperature reservoirs in between the source and the sink for a non-isothermal heat transfer process. We analyze the situation and conclude that such quasi-static processes are not reversible. Indeed, no non-isothermal heat transfer process can ever be made reversible due to an extraneous work term.
