“…It can be noted that the hot water temperature rose from the range of (50.8-76.5 ºC) to (59.3-87 ºC). This rise, in turn, has resulted in substantial enhancements in the thermal performance of the ETSC to produce hot water with higher temperature values to serve the residents in winter when nanomaterials are integrated into the solar collector [39,40]. Also, it is concluded that employing nanomaterials in the ETSC system helped achieve a significant elevation in the temperature values of the solar collector, which is shown in the 3D profile of the solar collector pipes in both cases.…”

This research is carried out to investigate and examine the critical benefits and significant contributions of integrating nanoparticles into the ETSC system to enhance the thermal efficiency, thermal performance, temperature out, and energy storage of the ETSC. The Simcenter STAR-CCM+ 2022.1 software package implemented numerical analysis and thermal simulations. Further, a comparative analysis is conducted on two case studies to validate the critical role and contributions of employing the aluminum oxide nanomaterial in the solar collector system to enhance its thermal efficiency and improve its thermal performance and heat transfer, including (1) conventional ETSC and (2) ETSC with Al2O3. According to the numerical analysis and comparative study findings, the results of this research revealed that employing and adding the aluminum oxide nanomaterial into the ETSC system had contributed to several beneficial impacts and significant advantages. In addition, using Al2O3 achieved enhancements in the thermal efficiency, increases in the outlet collector’s temperature, improvements in the rate of heat flux of the pipes, the tube inside the collector, heat transfer of the hot water storage tank, and a rise in the temperature gradient the hot water temperature increased from (between 44.3 and 74.8 ºC) to (between 49.6-80.3 ºC). Besides, the velocity of the water flow inside the solar collector in the second case in which the aluminum oxide nanoparticles are used was higher due to the absorption of further solar radiation and thermal energy, which resulted in a considerable increase in the kinetic energy of water molecules from 0.01 to 0.07 m/s. Also, it was found that the velocity directions and profile were slightly more turbulent in the second case than the conventional solar collector due to more thermal energy absorbed and stored in the ETSC from solar radiation.

“…As noted by Tiwari et al (1992), the water consumption of crops in protected cultivation fluctuates diurnally and seasonally, similar to the variation in productivity of solar desalination. As both processes are driven primarily by solar radiation, which is variable, consumption and provision are closely correlated.…”

“…The thermal efficiency of a solar thermal still can be improved by preventing heat losses to the environment [174]. Thus, an important design parameter is the selection of suitable insulating materials that can prevent heat escaping from the still [175]. Several studies have investigated the performance of various insulating materials like saw dust, glass wool, Styrofoam, polyurethane, fiber glass and nitrile rubber [59,65,110,113,176,177].…”

The demand for high-quality freshwater is increasing due to global population growth, intensifying agricultural practices and expanding industrial development. Additionally, many global regions have low levels of rainfall which makes them arid and incapable of supporting large human populations or agriculture. Currently, large quantities of fossil fuels are used to generate the power needed to drive energy intensive desalination processes that deliver high-quality freshwater to many of these regions. However, the use of fossil fuels has led to high greenhouse gas emissions, environmental degradation and global warming. Solar-thermal desalination is a low-cost, sustainable and eco-friendly strategy for producing high-quality freshwater without using energy derived from fossil fuels. However, in spite of recent developments to advance solar-thermal desalination, the most effective strategies for achieving higher performance levels still remains elusive. To tackle this problem, the present article reviews several solar-thermal still configurations, including materials, system design parameters, influencing factors and operational parameters. Moreover, recent material advances in plasmonic nanoparticle-based volumetric systems, nanomaterial enhanced phase change materials and interfacial solar evaporators are discussed. These new material advances can have the potential to significantly improve the conversion of light-to-heat, enhance vapor generation and promote greater water production rates.
