Abstract
In a classical endoreversible Carnot engine model, irreversibility in the form of heat resistance between the reversible Carnot cycle and its heat reservoirs is taken into account. This paper presents a generalized irreversible Carnot engine model that incorporates several internal irreversibilities, such as heat leak, friction, turbulence etc. These added irreversibilities are characterized by a constant parameter and a constant coefficient. The relation between optimal power output and efficiency is derived based on a generalized heat transfer law . The effect of heat leakage, internal irreversibility and heat transfer law on the optimal performance of the generalized irreversible heat engine is investigated.This publication has 14 references indexed in Scilit:
