The operational conditions of the endoreversible cycle considering the heat loss from the heat source

熱源의 熱損失을 考慮한 內的 可逆사이클의 運轉條件

The conventional model of the heat engine involves the inconsistency with the real engine that the power becomes to be zero at the maximum effectiveness condition. In order to improve this defect, a new model of the heat engine is proposed, in which the heat loss from the heat source is taken into account. In accordance with this model, both the power and effectiveness have their respective extremum with respect to operating conditions, and the effectiveness always becomes to be zero when the power is zero.
