The Influence of Internal Heat Leak on the Power versus Efficiency Characteristics of Heat Engines
Chen Lingen Sun Fengrui Chen Wenzhen
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.
