摘要
有机朗肯循环是中低品位热能高效回收和利用的重要技术手段,国家自然科学基金的资助可以反映我国科研工作者对有机朗肯循环相关领域关键问题的思考和判断。基于国家自然科学基金有机朗肯循环领域资助的知识图谱,梳理了该领域的基金批准数量、依托单位、资助类别、关键词分布、论文发表和专利申请情况。分析表明,自2009年以来,国家自然科学基金中,有机朗肯循环领域获批基金约78项,其中,天津大学、西安交通大学和清华大学获批的基金数量位列前三;我国有机朗肯循环的论文发表处于国际领先地位,但国际专利表现不足。从历年资助的数量和词频来看,有机朗肯循环的研究大致包括:匹配不同热源热力循环的热经济优化,工质筛选、实验研究和系统仿真,临界或超临界工况及耦合、复叠循环的研究,混合工质的物性分析及其设计,冷热电联供循环的架构及动态调控。未来有机朗肯循环的研究主题应更聚焦于膨胀机等关键部件的研制、工质物性量测及非共沸工质设计、耦合循环的构建及动态调控等,并加强产、学、研的合作交流,以推动有机朗肯循环关键技术的突破和应用。研究概览以期为从事中低温热功转换领域的青年学生和科研学者提供参考。
Organic Rankine cycle(ORC)is an important technology for the efficient utilization of low-andmedium-grade thermal energy.Funds from National Natural Science Foundation of China(NSFC)reflect researchers’thinking and judgment of critical issues with respect to ORC.Based on mapping knowledge domain of NSFC concerning ORC,this paper summarized the number of funding proposals,affiliated institutions,funding categories and keyword distribution,as well as published academic papers and patents.Results indicate that 78 research projects about ORC have been supported by NSFC since 2009,specifically Tianjin university,Xi’an Jiaotong university and Tsinghua university occupy the top three slots.In the recent decade,China takes the leading position regarding published papers of ORC;however,its performance of international patents is not completely sufficient.The research include:The analysis of matching various heat sources and thermo-economic optimization;The screening of working fluids,equipment experiments and system simulation;Critical or supercritical cycles and the coupling of ORC;Design of non-zeotropic mixtures and its property analysis,as well as the architecture of combined cooling,heating and power system and its dynamic control strategic.As for the future study,research subjects of ORC may focus on the development of key components such as expander,property measurement of working fluids and design of non-zeotropic mixtures,the construction and dynamic control strategic of coupling cycles,strengthening the cooperation and joint work between industry,university and research institute,as well as achieving the breakthrough and implementation of key technologies of ORC.This paper is intended to provide a reference for freshmen and scientific research scholars,who are dedicated to do research on energy conversion and management of medium and low temperature thermal energy.
