摘要

利用太阳能处理咸水为日益增长的全球淡水需求提供了一种可持续和低成本的解决办法。在这个方向上，太阳能蒸馏系统直接利用太阳辐射将水蒸气从盐水中分离出来，然后将其冷凝以获得纯净水。然而，它们的淡水生产力相对较低。因此，本研究对完全依靠太阳能发电的双斜面太阳能蒸馏装置和抛物面槽太阳能集热器的淡水产率和热效率进行了实验研究。此外，还研究了含多壁碳纳米管的水基纳米流体对太阳能蒸馏器性能的影响。对生产的所有蒸馏器进行了淡水产率和热效率的比较。研究结果显示，SSSS、DSSS、PTSC综合DSSS、NF和PTSC综合DSSS的日生产力分别为1963.8 g/m2/day、2008.5 g/m2/day、2592.0 g/m2/day和2937.6 g/m2/day。结果表明，DSSS、整合PTSC的DSSS和整合PTSC和NF的DSSS的日生产率分别比SSSS高6.6%、42.2%和49.6%。此外，我们还观察到使用PTSC和NF的DSSS的热效率比SSSS低，因为它的系统面积更大。

Experimental analysis of a double-slope solar still integrated with parabolic trough solar collector using nanofluid

The use of solar energy in the treatment of saline water offers a sustainable and low-cost solution to the increasing global fresh water demand. In this direction, solar still systems separate water vapor from saline water by directly using solar radiation and then condense it to obtain pure water. However, their fresh water productivity is relatively low. Therefore, in this study, the fresh water productivity and thermal efficiency of the double slope solar distillation unit integrated with parabolic trough solar collector, which operates completely on solar energy, were investigated experimentally. In addition, the effect of water-based nanofluid containing multi-walled carbon nanotubes on the performance of the solar still was investigated. All the stills produced were compared in terms of fresh water productivity and thermal efficiency. According to the results obtained from the study, the highest daily productivity was found to be 1963.8 g/m²/day, 2008.5 g/m²/day, 2592.0 g/m²/day and 2937.6 g/m²/day for SSSS, DSSS, PTSC integrated DSSS and both NF and PTSC integrated DSSS, respectively. It was observed that the daily productivity of DSSS, DSSS with integrated PTSC, and DSSS with both PTSC and NF were 6.6 %, 42.2 %, and 49.6 % higher than SSSS, respectively. Additionally, it was observed that the thermal efficiency of DSSS using PTSC and NF was lower compared to SSSS due to its larger system area.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
