非等温化学机的最大功率输出特性

Performance of a Non-isothermal Chemical Engine at the Maximum Power Output

基于内可逆非等温化学机的循环模型,综合考虑有限温差热传递和有限化学势差质量传递的不可逆性,导出了循环功率的一般表达式,进而讨论循环的最大功率输出特性以及传热传质不可逆性对最大输出功率的影响.

Based on the cycle model of a non-isothermal endoreversible chemical engine, the irreversibilities of heat and mass transfers resulting from both finite temperature and chemical potential differences are considered synthetically and the general expression of the power output of the cycle is derived analytically. The maximum power output characteristics of the cycle and the influence of the irreversibilities of heat and mass transfers on the maximum power output are discussed.
