Time dependent conduction heat transfer during solidification in a storage system using nanoparticles
In this research, nanofluid thermal behavior in an energy storage system is illustrated by means of FEM. CuO nanoparticles have been dispersed into the water to overcome the poor thermal conductivity. Role of Brownian motion is included for estimating characteristics of nanofluid. Results are shown as solid fraction, isotherm contours, average temperature and total energy profiles. Results showed that dispersing nanoparticles to pure PCM have important impact on heat transfer rate. As A and N enhances, total energy and solidification time decrease. Furthermore, in order to reach greatest solidification rate, nanoparticles with dp= 40 nm should be used.
