摘要：Due to the fact that the turbine outlet temperature of aeroderivative three-shaft gas turbine is low,the conventional combined cycle is not suitable for three-shaft gas ***,the humid air turbine(HAT)cycle provides a new choice for aeroderivative gas turbine because the humidification process does not require high *** HAT cycle plants are all based on single-shaft gas turbines due to their simple structures,therefore converting aeroderivative three-shaft gas turbine into HAT cycle still lacks sufficient *** paper proposes a HAT cycle model on a basis of an aeroderivative three-shaft gas *** HAT cycle modelling of saturator,gas turbine and heat exchanger are carried out based on the modular modeling *** models are verified by simulations on the aeroderivative three-shaft gas *** results show that the studied gas turbine with original size and characteristics could not reach the original turbine inlet temperature because of the introduction of ***,the efficiency still increases by 0.16%when the HAT cycle runs at the designed power of the simple ***,simulations considering turbine modifications show that the efficiency could be significantly *** results obtained in the paper can provide reference for design and analysis of HAT cycle based on multi-shaft gas turbine especially the aeroderivative gas turbine.

摘要：Saturator is one of the core components of humid air turbine （HAT） and is the main feature of HAT making it different from other gas turbine cycles. Due to the lack of sufficient experience in commercial plant operation, HAT cycle has a great demand for modeling and simulation of the system and its components, especially the saturator, to provide reference for system design and optimization. The conventional saturator models are usually based on the theory of heat and mass transfer, which need two accurate coefficients to ensure convincing results. This work proposes a global heat and mass transfer coefficient based on cooling tower technology to model the saturator in small-scale HAT cycle. Compared with the experimental data, the simulation results show that the proposed model well predicts the dynamic humidity and temperature distribution characteristics of saturator at low air pressure and temperature.

摘要：MnO_(2)作为超级电容器电极材料具有理论比电容高、成本低、环境友好等优点,但其低导电性和低利用率阻碍了其潜在应用.本研究首先在柔性碳布上电化学生长ZnO纳米棒阵列作为电极衬底,然后通过阳极电沉积法在ZnO纳米棒阵列表面外延生长了Mo和碳纳米管(CNTs)共掺杂的MnO_(2)薄膜,可控构筑了有效、高导电性的MnO_(2)纳米阵列电极(定义为ZnO@Mo-CNT-MnO_(2)NA).柔性ZnO@Mo-CNTMnO_(2)NA电极在100 A g^(-1)的大电流充放电密度下比电容可达237.5 F g^(-1),10,000次循环后电容保留率高达86%.采用ZnO@Mo-CNTMnO_(2)NA电极组装成水系非对称超级电容器,弯曲状态下在132.35 mW cm^(-3)(5mA cm^(-2))高功率密度下获得了1.13 mW h cm^(-3)的高能量密度,5mA cm^(-2)充放电倍率下循环7600次后电容保留率高达88%.本研究构筑的MnO_(2)基纳米阵列电极结构可提高其电导率和利用率,为柔性金属氧化物超级电容器电极的设计与制备提供新途径.
