Bibliometric Analysis of Global Trends on the Use of Nanofluids in Solar Thermal Systems

Abstract

A bibliometric analysis was conducted on the use of nanofluids in solar thermal systems. A total of 753 English-language documents indexed in the Scopus database between 2004 and 2024 were collected. The analysis shows sustained growth in research on the use of nanofluids in solar thermal systems, consolidating it as a dynamic and multidisciplinary field, led by Asia, especially India and China. Institutions such as Shanghai Jiao Tong University and Jiangsu University stand out for their productivity and collaboration. Works such as those by Mahian O., Saidur R., and Taylor R. A. are the most cited and influential, while new authors such as Zafar Said and Jamshed Wasim promote innovative approaches. Frequent keywords such as "nanofluids," "solar heating," and "thermal conductivity" reflect the interest in improving the thermal performance of these systems through the application of nanotechnology. Journals such as Solar Energy and Renewable and Sustainable Energy Reviews are leading the way, and emerging topics in magnetohydrodynamics and nanofluid flow offer new research opportunities.
