| 摘 要： | 提出了回热式布雷顿-两平行逆布雷顿联合循环模型。对该模型进行了第一定律性能分析与优化，得出了该循环最优效率和最优比功的表达式，分析了回热度及其他参数对联合循环最优热效率和最优比功的影响。分析表明，增加回热器后能提高联合循环的热效率，但此时联合循环的输出比功较小。

| Abstract: | A combined regenerative Brayton and inverse Brayton cycles is proposed. The first law analysis and optimization for the combined cycle is performed. Analytical formulae about optimal thermal efficiency and optimal specific work are deduced. Moreover, the effects of regenerator and other parameters on the performance of the combined cycle are analyzed. It is found that the combined regenerative cycle can obtain higher thermal efficiency than that of the base cycle but smaller work output. |
