“…Various nanofluids can considerably improve the base fluid's thermophysical properties, enhancing the heat transfer efficiency of thermal processes. Simple and hybrid nanofluids are employed in STSs, such as parabolic trough collectors and solar collectors [79], water-heating systems [80], water desalination [15,81], evacuated tubes [82], and photovoltaic/thermal (PVT) systems [83], focusing on the life cycle methodology [84].…”

The use of solar thermal systems (STSs) has recently reached a significant edge. The increasing research on developing an alternative power supply for limiting fossil fuel usage and climate change are the driving forces of STSs. The current work explores the recent progress in STSs’ applications, including PV/T or “photovoltaic/thermal” systems, zero-energy buildings, greenhouse solar thermal applications, solar thermal for pumping water, solar thermal refrigerators, solar chimneys, water desalination, and solar collectors, along with the benefits and challenges of these applications. Then, the potential contribution of STSs in achieving the various SDGs or “Sustainable development goals”, including barriers and research gaps, are elaborated. In brief, STSs significantly contribute to the seventeen SDGs’ achievement directly and indirectly. Recent developments in the engineering applications of STSs are strongly based on the materials of construction, as well as their design, process optimisation, and integration with multidisciplinary sciences and technologies such as modelling, nanoscience/nanotechnology, and artificial intelligence.

“…Recent studies [48,49] indicate that nanofluids can be used specifically in low optical and thermal performance solar energy conversion systems to boost their performance. Kabeel et al [50] investigated thermal solar water heater with Al 2 O 3 /H 2 O nanofluid in forced convection, and their results showed an increased solar collector efficiency of 11% for 3% nanoparticle concentration. An enhancement of 21% in average heat transfer coefficient was reported by Ebrahimnia et al [51] after conducting laminar flow convective heat transfer experiments of water-based TiO 2 nanofluid flowing through a uniformly heated tube.…”

The twenty-first century is experiencing a wave of technologies and innovations making use of unique features of nanofluids, in applications such as industrial and process heating, air conditioning and refrigeration systems, heat pipes, solar energy, thermal storage systems, electronic cooling systems and others. Recent literature indicates that suspending solid nanoparticles in traditional working fluids can enhance heat transfer rates by increasing thermal conductivity and heat transfer coefficients. However, there is a wide variation in the extent of heat transfer enhancements reported in the literature. In this review, which mainly focuses on the research published within the last 5 years, experimental investigations from recent developments of nanofluids usage and performance in various heat transfer systems are summarised. In addition, heat transfer mechanisms in nanofluids, the challenges and future direction of nanofluids regarding heat transfer enhancement are discussed. Popular preparation methods of nanofluids and the models of thermophysical properties such as thermal conductivity and viscosity have been reviewed.

[1][2][3][4][5][6][7][8] Krishnavel et al 9 experimentally investigated concrete absorber solar water heater with and without insulation at different inclination angles. Also, experiments were carried out with polyvinyl chloride (PVC) pipes and aluminum pipes with wire mesh and iron scraps.…”

This study communicates the performance analysis of spiral and serpentine tube solar collector with carbon nanotube nanofluids under natural flow method. Experiments were carried out at three different mass flow rates namely 3, 5, and 7 kg/hour while the concentration of nanoparticles was varied from 0.05% and 0.1%, respectively. Experiments were carried out under the same condition of ambient parameters for validation. Results show that the maximum exit water temperature was found to be about 75°C with a maximum concentration of 0.1% under a minimum flow rate of 3 kg/hour during the peak intensity. Similarly, the improvement in temperature of the water is found to be 6% under peak intensity and decreased to about 4.3% and 4.2% for the flow rates of 5 and 7 kg/hour, respectively
