两类循环模式下不可逆热机装置的有限时间热力学优化

Finite Time Thermodynamic Optimization of Irreversible Heat Engine Plant in Two Cycle Mode

本文对具有有限热容流率的两热源间包含内部不可逆效应的卡诺循环热机装置的有限时间热力学优化问题进行了分析，在两种不同热交换模型下推导出不可逆卡诺循环热机装置在有限时间内的最佳功率及热效率的理论公式。

Finite time thermodynamic optimization of internal irreversible Carnot cycle heat engine plant operating between two reservoirs with finite heat capacity rates are present analytically.The optimum power and efficiency of real Carnot engine operating in two kinds of heat exchange cycle modes are obtained.Some new performance limits of the finite time thermodynamics,which provide a useful guide to the design and estimation of actual heat engine plant.are derived.
