Efficiency of inefficient endoreversible thermal machines
摘要:
我们提出了一个研究的性能优化的内可逆热机的热力学力与冷浴在小热力学力的制度。这些热机既可以作为发动机,也可以作为制冷机。我们分析了如何确定的热力学通量的依赖力的最佳性能。结果的动机和说明的量子模型,三能级脉塞,并给出了明确的解析表达式的引擎效率作为系统参数的函数。
英文摘要:
We present a study of the performance of endoreversible thermal machines optimized with respect to the thermodynamic force associated with the cold bath in the regime of small thermodynamic forces. These thermal machines can work either as an engine or as a refrigerator. We analyze how the optimal performances are determined by the dependence of the thermodynamic flux on the forces. The results are motivated and illustrated with a quantum model, the three level maser, and explicit analytical expressions of the engine efficiency as a function of the system parameters are given.
