“…Nanofluids have improved thermo-physical properties such as density, thermal conductivity and more, which increased the heat transfer rate. Hussein et al [64] and Singh et al [65] concluded that nanofluids play a crucial role for efficient heat transfer and power generation which is a significant part of desalination and utilizing nanofluid based heat transfer will reduce water production costs. Sharon et al [66] and Reif et al [67] reported that while traditional solar systems were designed for electricity production, modified systems with advanced heat transfer characteristics are necessary, in order to satisfy present energy and water needs globally.…”

Desalination accounts for 1% of the total global water consumption and is an energy-intensive process, with the majority of operational expenses attributed to energy consumption. Moreover, at present, a significant portion of the power comes from traditional fossil fuel-fired power plants and the greenhouse gas emissions associated with power production along with concentrated brine discharge from the process, pose a severe threat to the environment. Due to the dramatic impact of climate change, there is a major opportunity to develop sustainable desalination processes to combat the issues of brine discharge, greenhouse gas emissions along with a reduction in energy consumption per unit of freshwater produced. Nanotechnology can play a vital role to achieve specific energy consumption reduction as nanofluids application increases the overall heat transfer coefficient enabling the production of more water for the same size desalination plant. Furthermore, concentrated brine discharge has a negative impact on the marine ecosystems, and hence, this problem must also be solved to support the objective of sustainable desalination. Several studies have been carried out in the past several years in the field of nanotechnology applications for desalination, brine treatment and the role of renewable energy in desalination. This paper aims to review the major advances in this field of nanotechnology for desalination. Furthermore, a hypothesis for developing an integrated solar thermal and nanofluid sustainable desalination system, based on the cyclic economy model is proposed.

Nowadays, nanotechnology is one of the most conducting research-based areas because it merges understanding from many disciplines such as Physics, Chemistry, Biology, Medicine, Engineering, and Environmental Sciences among others. There are no limits to the potential applications of nanotechnology. It is helping to considerably improve, even revolutionize, many technology and industry sectors. New nano-and bio-materials, and nano-devices, are produced and monitored through nanotechnology instruments and manners, which explore and transform the features, responses, and functions of living and non-living matter, at sizes below 100 nm. This review focuses on nanotechnology, its definition and applications, and sunlight as a driving tool for developing nanotechnology. Sunlight as a free source of energy and clean agent for several physical and chemical reactions constitutes an increasing interest for both science and technology. Nanotechnology should focus on more using sunlight as a free energy source and an environmentally-friendly agent for its advancing for the human kind best future.

The numerical investigation of the natural convection in concave and convex parabolic enclosures with a nanofluid consisting of water and copper nanoparticles is carried out by using the finite volume method. The upper and lower walls of the enclosures are adiabatic while the sidewalls are isothermal at a cold temperature. An internal heat source of constant length (ε = 0.2) and negligible thickness is placed at various vertical positions along the center of the enclosure. It was found that the increase in the location of the heat source leads to a drop in the water and nanofluid flow circulation in both types of enclosures. For both considered Cases I and II, the average Nusselt number increases when the Rayleigh number and solid volume fraction increase. Moreover, it was concluded that Case I with δ = 0.8 is the optimum case for heat transfer enhancement for Ra = 103 and Ra = 104. Case II with δ = 0.5 is optimum for Ra = 105. Both cases are satisfied when the nanofluid is used with ϕ = 0.2.
