摘要
本文研究热漏对热机最优性能的影响,导出存在热阻和热漏损失的定常态流不可逆热机的功率、效率关系。所得结果不同于仅存在热阻损失时的内可逆热机的功率效率特性,且与实际热机特性相一致。
The influence of internal heat leak on the optimal performance of heat engines is studied in this paper. The relation between optimal power output and efficiency for a steady-state irreversible heat engine with irreversibilities of external heat resistance and internal heat leak is derived. The power versus efficiency characteristics obtained here is qualitatively different from that for an endoreversible heat engine and is in agreement with that for a real heat engine.
