论文摘要
尽管具有理想化，但热力学已经证明了其作为实践应用的预测理论的力量。特别是，Curzon-Ahlborn效率为任何具有最大功率运行的实际发动机提供了基准。在这里，我们进一步开发了可耐腐烂的奥托引擎的分析。对于一类通用的工作培养基，其内部能量与温度的某些功率成正比，我们发现没有发动机可以在有限的功率下实现Carnot效率。但是，我们还发现，对于光子发动机的特定示例，最大功率的效率大于库尔松 - 阿尔伯恩效率。
Despite its idealizations, thermodynamics has proven its power as a predictive theory for practical applications. In particular, the Curzon-Ahlborn efficiency provides a benchmark for any real engine operating at maximal power. Here we further develop the analysis of endoreversible Otto engines. For a generic class of working mediums, whose internal energy is proportional to some power of the temperature, we find that no engine can achieve the Carnot efficiency at finite power. However, we also find that for the specific example of photonic engines the efficiency at maximal power is larger than the Curzon-Ahlborn efficiency.
