另一类线性传热时热漏和有限热源对两热源热机最优构型的影响

在一类存在热漏和有限高温热源的两热源热机的基础上，考虑传热服从另一类线性定律Ｑ∝△（Ｔ－１），寻求其给定循环周期下的最优构型．结果表明，对无限热容热源情形，热漏的存在不改变循环的最优构型；对有限热容热源情形，无热漏使循环构型成为某种“广义卡诺循环”，而存在热漏时，循环的构型则完全不同．同时，给出了各种不同情况下热机的最佳功率效率关系．

Effect of heat leak and finite thermal capacity on the optimal configuration of a two-heat-source heat engine in the case of another linear heat transfer law

Based on the model of a two-heat-source heat engine with a finite high-temperature source and bypass heat leak, the optimal configuration of the cycle is found for the fixed period with another linear heat transfer law [i.e., It is shown that heat leak doesn't change the optimal configuration of the cycle. The finite thermal capacity source without heat leak makes the configuration of the cycle to a class of generalized Carnot cycle. The configuration of the cycle with heat leak and finite thermal capacity source is different from those three cases. Moreover, the relations between the optimal power output and the efficiency for various cases are deduced.
