An irreversible Maisotsenko reciprocating Brayton cycle (MRBC) model is established using the finite time thermodynamic (FTT) theory and taking the heat transfer loss (HTL), piston friction loss (PFL), and internal irreversible losses (IILs) into consideration in this paper. A calculation flowchart of the power output (P) and efficiency (η) of the cycle is provided, and the effects of the mass flow rate (MFR) of the injection of water to the cycle and some other design parameters on the performance of cycle are analyzed by detailed numerical examples. Furthermore, the superiority of irreversible MRBC is verified as the cycle and is compared with the traditional irreversible reciprocating Brayton cycle (RBC). The results can provide certain theoretical guiding significance for the optimal design of practical Maisotsenko reciprocating gas turbine plants.
本文运用有限时间热力学（FTT）理论，考虑传热损失（HTL）、活塞摩擦损失（PFL）和内部不可逆损失（IIL），建立了不可逆迈索森科往复布雷顿循环（MRBC）模型。给出了该循环功率输出（P）和效率（η）的计算流程图，并通过详细的数值算例分析了向循环中注水的质量流量（MFR）以及其他一些设计参数对循环性能的影响。此外，验证了不可逆MRBC循环的优越性，并将其与传统不可逆往复布雷顿循环（RBC）进行了比较。研究结果可为实际迈索森科往复式燃气轮机装置的优化设计提供一定的理论指导意义。
