“…Their theoretical results indicated that the efficiency of a concentrating solar collector based on a nanofluid (Al 2 O 3 /Water) could be higher by about 5-10% than a conventional parabolic solar collector. Karami et al [26] conducted an experimental study to investigate the CuO nanofluid-based direct absorption solar collector for residential applications. Their results showed that the thermal efficiency of the flat plate collector using nanofluids could be improved by 9-17% relative to the base fluid.…”

“…In recent years, some studies have shown that the dispersion of metal nanoparticles [6] and carbon-based composites [7] into heat transfer fluids can improve the optical absorption properties of working fluids. However, the specific heat capacity of such a working fluid is so small that it is impossible to store too much energy, resulting in inefficient reception efficiency.…”

In this study, In-situ precipitation reaction was used to prepare paraffin@SnO 2 /CNTs composite phase change materials. The paraffin@SnO 2 /CNTs composites material were prepared by using paraffin as a phase change core material, and tin dioxide and carbon nanotubes as composite shell materials. The microstructure, chemical composition and crystal phase structure of the composites were analyzed by Scanning electron microscope (SEM), Fourier infrared spectrum (FT-IR) and X-ray diffraction (XRD). The thermal performance and thermal stability of phase change materials were determined by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The microcapsule has a core-shell structure with a diameter of 2-5 μm. The encapsulation efficiency of the paraffin@SnO 2 /CNTs composite was calculated to be 42.94%. The slurry is formed by dispersing microcapsules in water, which not only greatly improves the specific heat capacity, thermal conductivity, visible light absorption, but also makes the effective receiving efficiency reach 91.79% at 40°C, indicating that it is a promising heat transfer working slurry in the field of Direct Absorption Solar Collectors (DASC) system.

“…Otanicar et al [1] reported enhancement of the collector efficiency by 7% when 0.25% wt of 20 was dispersed in water in comparison with a "black surface" absorber. Karami et al [2] succeeded in improving the photothermal performance of their solar collector by 25% using 20 at 0.01% wt.…”

The process of photo thermal evaporation in nanofluids finds promising applications in solar energetics, medicine and process technology. Previous studies report highly efficient production of solar steam in fluids with gold nanoparticles. In thi article, we establish the process in nanofluids with less expensive carbon black (CB) and iron oxide (IO) nanoparticles (NP). Screening the concentration of nanoparticles, we tailor the nanofluids to reach the efficiency maxima: 66% at 3% wt. (CBNP) and at 10% wt (IONP); the steam was superheated up to 10 K (CBNP) and 16 K (IONP). It was also discovered that the IONPs-generated steam was contaminated with nanoparticles. In addition to experimental results, we have developed an empirical model of photo-thermal steam generation in nanofluids. The model agrees well with the experiments.KEYWORD: solar steam, nanofluid, boiling, carbon black, iron oxide I.
