Nanofluids have opened the doors towards the enhancement of many of today’s existing thermal applications performance. This is because these advanced working fluids exhibit exceptional thermophysical properties, and thus making them excellent candidates for replacing conventional working fluids. On the other hand, nanomaterials of carbon-base were proven throughout the literature to have the highest thermal conductivity among all other types of nanoscaled materials. Therefore, when these materials are homogeneously dispersed in a base fluid, the resulting suspension will theoretically attain orders of magnitude higher effective thermal conductivity than its counterpart. Despite this fact, there are still some challenges that are associated with these types of fluids. The main obstacle is the dispersion stability of the nanomaterials, which can lead the attractive properties of the nanofluid to degrade with time, up to the point where they lose their effectiveness. For such reason, this work has been devoted towards providing a systematic review on nanofluids of carbon-base, precisely; carbon nanotubes, graphene, and nanodiamonds, and their employment in thermal systems commonly used in the energy sectors. Firstly, this work reviews the synthesis approaches of the carbon-based feedstock. Then, it explains the different nanofluids fabrication methods. The dispersion stability is also discussed in terms of measuring techniques, enhancement methods, and its effect on the suspension thermophysical properties. The study summarizes the development in the correlations used to predict the thermophysical properties of the dispersion. Furthermore, it assesses the influence of these advanced working fluids on parabolic trough solar collectors, nuclear reactor systems, and air conditioning and refrigeration systems. Lastly, the current gap in scientific knowledge is provided to set up future research directions.

“…Moreover, they concluded that adding nanoparticles with smaller diameter is more efficient in the solar still. In another investigation, Sahota et al [71] repeated this analysis and performed the exergoeconomic and enviroeconomic analyses for this problem. They used CuO and Al2O3 nanoparticles.…”

In recent years, nanofluids have been widely used to improve the performance of various energy systems due to their favourable thermo-physical and optical characteristics. In particular, solar distillation systems, as an affordable and reliable technique to provide freshwater, have benefited from nanofluid technology. This article performs a review of literature on the implementation of nanofluid technology in active and passive solar distillation systems. The progress made and the existing challenges are discussed and some conclusions and suggestions are made for future research. The review indicates that the daily productivities of solar distillation systems enhance by using nanofluid and increasing the volume fraction of nanoparticles. However, long-term operational stability and life cycle assessment remain critical issues. These factors should be considered for future research in this field.

Solar distillation is a method of thermal desalination in which water is evaporated using solar energy and the separated water vapor is condensed again as pure water. This is a good practical alternative in offering a renewable energy source that is used to produce clean water in areas where there is a lack of clean water. This study aims to obtain the results of the amount of thermal energy obtained from a passive solar desalination system with a double slope and the factors that greatly affect the amount of thermal energy in the system. In this study, the method used for data collection was an experiment carried out for eight days. From the research results, the highest thermal energy produced is 9.18 kWh and the lowest is 1.23 kWh, and the factors that affect the amount of thermal energy are the heat transfer coefficient and the amount of distilled water produced by the system. By knowing the amount of thermal energy produced by the system, areas that have a lack of clean water can use a passive solar desalination system with a double slope that uses solar energy as its energy source.
