摘要
将弱耗散假设应用于由两个绝热过程和两个多方过程组成的一类广义卡诺热机循环,求出了循环的输出功率与效率的表达式,并给出了循环在最大输出功率时效率的上下界限,由此讨论了这一类循环的性能特性.
The weak-dissipation assumption is used to the model of a class of generalized Carnot heat engine cycles composed of two adiabatic and two polytropic processes, from which the expressions for the power output and efficiency of these cycles are derived. The lower and upper efficiency bounds of these cycles at the maximum power output are determined and the performance characteristics of these cycles are discussed.
