“…Olia et al [16] examined the use of copper nanoparticles led to improve thermal efficiency in metallic nanofluids, followed by CuO, TiO2, and Al2O3, among all the nanoparticles examined, the MWCNT nanoparticle can lead to the highest increase in thermal efficiency for non-metallic nanofluids. Mirabootalebi et al [20] altering the effective variables, such as increasing milling time, selecting the suitable temperature, utilizing different sizes of balls, and using a special vial, can increase the quality and quantity of MWCNTs. Three essential components of the experiments conducted and described in this article are innovative.…”

Solar thermal systems for heating have a high level of reliability. The usage of parabolic trough collectors (PTC) for domestic applications is still quite limited; furthermore, commercial utilization of nanofluids in these applications is rare. The influence of MWCNT nanofluid as a heat transfer fluid on the efficiency of a locally developed parabolic trough collector was experimentally examined. The effect of surfactant on nanofluid stability was also investigated, and it was revealed that nanoparticles could be evenly suspended in base fluid for at least 10 days and less than one month using Triton X-100. Experiments were also conducted to determine the optimal quantity of Triton X-100 surfactant; it is possible to make nanoparticles stable for 28 days in base fluid with the ratio of Triton X-100 to MWCNT as 0.5:1. At 2.0, 3.0, and 4.0 L/min flow rates, MWCNT/H2O is used at three-particle concentrations of 0.1, 0.2, and 0.3% by weight. The experiment is carried out under outdoor operating conditions. With 3 L/min at 0.2 wt.%, MWCNT nanofluid achieves a maximum thermal efficiency that is 22% greater than the water. The findings provide important information about the commercialization of a locally developed PTC.
