摘要
超临界二氧化碳(SCO_2)在近临界点的物性特点异于常规工质,使得其动力循环方案与常规工质不同,循环的热力特性也有差异。综述了SCO_2闭式布雷顿循环系统实验研究的循环方案以及相关的研究现状和有关进展,专门针对其实验的关键技术,就系统循环方案的选择及相关实验研究结果进行了总结与分析,分析结果可为SCO_2闭式布雷顿循环系统实验平台循环方案的选择、设计,实验平台的搭建及实验等方面的研究提供参考。
The physical properties of supercritical carbon dioxide（SCO2）near critical point is different from that of conventional working fluids,therefore,the power cycle scheme and thermodynamic characteristics of the SCO2 closed Brayton cycle are also different.The situation and progress of the research on the cycle scheme in SCO2 closed Brayton power cycle experimental research are overviewed.For the key technologies of the experiment,the selection of cycle scheme and related experimental research results are summarized and analyzed respectively.The results can provide references for the selection and design of cycle scheme of SCO2 closed Brayton cycle experiment,as well as the construction and experiment of the platform.
