| Abstract | Nanoparticles were prepared and incorporated into molten salts to form a nanofluid system for use in a concentrated solar powerplant (CSP). Particle sizes of both the nanoparticles and incorporated molten salts were analyzed from images captured by scanning electron microscopy using image processing software. The heat transfer fluid was prepared via a two-step method by blending four molten salts (KNO3, NaNO3, LiNO3, and Ca(NO3)2.4H2O) and anodic aluminum oxide (AAO) at 180°C for 360 minutes. Results showed that after the anodization process, aluminum A5052 transformed the film surface into metal oxide (anodic aluminum oxide) with particle size smaller than 56.3 nm. Incorporation of aluminum nanoparticles into the molten salt matrix increased particle size to 100 nm due to the chemisorption of molten salt by hydroxide functional groups on the AAO surface during the heat transfer process. Addition of AAO improved the discharge power provided by the upright thermocline tank. |
