Effect of heat transfer law on the performance of a generalized irreversible Carnot engine

In it classical endoreversible Carnot engine model, irreversibility in the form of heat resistance between the reversible Carnot cycle and its heat re servoirs is taken into account. This paper presents a generalized irreversi ble Carnot engine model that incorporates several internal irreversibilitie s, such as heat leak, friction, turbulence etc. These added irreversibiliti es are characterized by a constant parameter and a constant coefficient. Th e relation between optimal power output and efficiency is derived based on a generalized heat transfer law Q proportional to Delta(T-n). The effect of heat leakage, internal irreversibility and heat transfer law on the optima l performance of the generalized irreversible heat engine is investigated.
