TL;DR: In this article, the initial stage of steam generation is mainly caused by localized boiling and vaporization in the superheated region due to highly non-uniform temperature and radiation energy distribution, albeit the bulk fluid is still subcooled.

TL;DR: In this article, a well-controlled experiment was performed using three different categorised nanofluids, i.e., gold, copper, carbon black, and their hybrids, to assess their performance in terms of photothermal conversion efficiency (PTE), specific absorption rate (SAR), and materials cost.

TL;DR: In this article, the authors compared the performance of gold and carbon black nanoparticles in terms of evaporation rate, materials cost and energy consumption, and concluded that gold nanoparticles are not feasible for solar evapotion applications, where the cost of producing 1 g/s vapour is ∼300 folds higher than that produced by carbon black nanofluids.

TL;DR: In this paper, an extensive experimental study was carried out with different sample nanofluids under a solar simulator, and the experimental results showed that the solar energy absorption performance of the hybrid nano-materials with plasmonic nanomaterials is much better than that of nanofl fluids with non-plasmonics, i.e., Fe3O4 and DI water, due to the effect of localized surface Plasmon resonance.

TL;DR: In this article, a computational fluid dynamics (CFD), non-isothermal, three-dimensional detailed model has been developed to simulate and analyze the fluid flow and heat transfer physiognomies.
