基于知识图谱的槽式太阳能集热器研究可视化计量分析

Visual bibliometrics analysis of parabolic trough solar collector investigation based on knowledge mapping

作为重要的绿色节能技术,槽式太阳能聚光集热器在中低温太阳能热利用领域中具有良好的应用前景。基于Web of Science数据库,借助可视化工具VOSviewer和Citespace软件对全球槽式集热器领域研究文献进行了统计梳理,全面分析了该研究领域的研究态势、发展历程以及研究热点。结果表明全球槽式集热器领域发展整体呈现增长态势,发文量逐年攀升,但该领域不同团队之间的合作较少,以团队内部成员合作居多;聚类分析表明研究主要集中在有机朗肯循环、聚光太阳能发电以及纳米流体研究等方面,且近年来通过建立数理模型对槽式集热器系统进行性能优化已成为主要研究热点。

As an important clean and energy-saving technology,the parabolic trough solar concentrating collector has a good application prospect in the field of medium and low temperature solar thermal utilization.Based on the Web of Science database and with the help of visualization tools(i.e.,VOSviewer and Citespace software),an overall review of the research literature in the field of global parabolic trough solar collector investigation is conducted.The research trend,development history and research hotspots are comprehensively analyzed.Results show that the development of global parabolic trough solar collector research field presents an overall growth trend,and the number of published papers has increased year by year.However,little cooperation between various authors is presented,therefore the core team in this field has not yet formed.In addition,the cluster analysis shows that the research mainly focuses on organic Rankine cycle,concentrating solar power generation,nanofluid and etc.Furthermore,the parabolic trough solar collector system has been evaluated by establishing mathematical and physical models,and the performance optimization has become a major research hotspot in recent years.
