“…The suspensions were prepared using the conventional two-step method, which is usually used to produce nanofluid [22,23]. First, the initial dry nanopowder was added into the base fluid, and then the resulting suspension was mixed using an ultrasonic homogenizer MEF93.T from MELFIZ (Moscow, Russia).…”

“…The statistical uncertainty is due to averaging the flow rate over time during the measurement duration; it is determined concerning a confidence interval of 95%. The instrumental error of the flow meter is determined according to the methodology given in [22]. The total uncertainty of measuring the steam flow was calculated following the standard technique as…”

“…For further analysis of the obtained results, it is convenient to evaluate the evaporation efficiency, which is commonly used to assess the efficiency of solar steam generation [17,22,31,32]. Evaporation efficiency η is the ratio of the energy spent on the evaporation of the liquid to the total heat supplied to the system:…”

Due to the high light absorption and the possibility of localizing boiling to the interior of the receiver, nanoparticles are promising for solar-driven desalination. The paper presents an experimental study of the nanoparticle-based photothermal boiling of water with sea salt. The experiments were carried out using a laboratory-scale system with a transparent photothermal receiver of light and a closed condensate cycle. In this study, we tested three types of nanoparticles: multiwall carbon nanotubes with two main sizes of 49 nm and 72 nm, 110 nm iron oxide particles Fe3O4, and a commercial paste based on carbon nanotubes. The concentration of nanoparticles was varied up to 10% wt. We found that the nanoparticles enhance the steam generation by 23%, relative to a conventional desalinator with a black-body receiver. The best result was obtained for the 5% wt. concentration of carbon nanotubes.

Nanoparticles have been thoroughly investigated in the last few decades because they have many beneficial and functional qualities. Their capability to enhance and manipulate light absorption, thermal conductivity, and heat transfer efficiency has attracted significant research attention. This systematic and comprehensive work is a critical review of research on the photothermal energy conversion performance of various nanofluids as well as the recent advances in several engineering applications. Different nanofluids used in the photothermal energy conversion process were compared to identify the suitable applications of each nanofluid in thermal systems. An analysis of the previous investigations based on experimental and numerical studies has established that nanomaterials have the potential to increase the efficiency of solar thermal systems.
