This study presents a research on the use of nanofluids in solar thermal systems. The aim of this study is to investigate the potential benefits of using nanofluids, such as increased efficiency and reduced costs. Nanofluids are a type of fluids that contain nanoparticles capable of enhancing thermal properties. The thermal efficiency of systems using nanofluids has been observed to be higher compared to systems using water as the working fluid. In this study, solar thermal energy and systems, nanofluids and their structures, integration of nanofluids into solar thermal systems, and the positive and negative effects of nanofluid usage in these systems were examined, highlighting the necessity of their integration. Furthermore, the study demonstrates that the use of nanofluids can reduce the size of the solar collector required to achieve the same performance level, which can lead to a decrease in the overall cost of the solar thermal system. The results of this study indicate that the use of nanofluids in solar thermal systems can significantly enhance efficiency and reduce costs. However, further research is needed to fully explore the benefits and limitations of using nanofluids in solar thermal systems

This study concentrates on investigating the implementation of a heat pipe system experimentally and theoretically by simulating a novel heat pipe model employing the MATLAB/Simulink® program, R2021a, using nanofluids obtained by adding 0.5 wt.% and 1 wt.% nickel ferrite, iron oxide, and ferric oxide magnetic nanoparticles to distilled water. A thermal-network dynamic representative was suggested to illustrate the thermal behavior of the heat pipe. The simulated system was capable to indicate the transient demeanour and steady-state temperature of the two-phase closed thermosyphon accurately. The experimental and simulated outcomes demonstrated that the best performance was accomplished using NiFe2O4/DW magnetic nanofluid with a proper deviation of ± 3.52%. Furthermore, the efficiency, thermal resistance, and Nusselt number of the system were boosted by approximately 22.24%, 9.3%, and 51.9% while utilizing NiFe2O4 magnetic nanofluid corresponding to distilled water at 1 wt.%. A feedback control PID approach is assumed to perform a response within a fraction of a second as well as zero overshoot. The originality of the study is to experimentally and theoretically reveal the thermal behavior of NiFe2O4 containing Ni and Fe and the thermal behavior of the only Fe-containing nanofluid compared to the nanofluids obtained with magnetic particles such as Fe2O3 and Fe2O4
