摘　　要：用有限时间热力学方法分析内可逆恒温热源中冷回热布雷顿循环,由数值计算给出了燃气轮机功率密度特性,分析了循环各热力参数对功率密度的影响,并对最大功率密度和最大功率时循环的主要参数进行了比较,得出了最大功率密度设计的优点和不足。The theory of finite time thermodynamics is used in the analysis of an endoreversible closed intercooled regenerated Brayton cycle coupled to constant temperature heat reservoirs. The power density characteristics of the cycle are derived. The effect of thermodynamic parameters of the cycle on the power density has been analyzed through numerical calculation. The advantages and disadvantages are obtained from the comparison of the main parameters of the cycle at the maximum power and maximum power density.
