Several researchers suggested different alternatives for concentrated solar thermal and power systems. Among the various PTC alternatives, Semi-Parabolic Linear Fresnel Reflector (SPLFR) is considered a promising design to tackle the issue of manufacturing float glass mirrors in developing countries. In this study, an optical investigation was performed for different parameters of the SPLFR. With fixed strip mirrors widths of 45 mm, the heat flux was less affected by optical errors for a rim angle of 100°. Coupling errors have resulted in a compensation effect from which it was deduced that a control for non-random errors should be carried out for a better flux distribution. A displacement error of 6.2 mm with an offset angle of 45° has enhanced the optical efficiency for collecting rays diverged by the tracking error, thus an efficiency of 79% could be reached. This study also shows preliminary experimental results of a locally constructed SPLFR system.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133619405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of this new technology may call into question the reliability of the system, which is directly related to the device aging. Among factors that can influence component aging is temperature.

It can be converted to useful heat using solar thermal collector. Nowadays, solar parabolic trough collector (PTC) is considered as an excellent alternative among solar concentrators. In the current study, a transient numerical analysis is carried out to investigate the performance of Solar-PTC integrated with storage tank using various nanofluids as heat transfer fluids in southern Tunisia climate. The effects of weather data, storage tank volume and adding nanoparticles as alumina (Al2O3) and copper (Cu) into pure thermal oil (Therminol-VP1) are taken into account on the modeling of the system. The numerical results were validated with experimental data reported in the literature and a good agreement was obtained proving that the mathematical model used in the present study is feasible and reliable. We found that the emerging of Cu particles in the Therminol-VP1 showed a higher peak temperature value even at low mass fraction when compared to the %Al2O3-VP1.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125460036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
