Acceleration of solidification process by means of nanoparticles in an energy storage enclosure using numerical approach
In this article, simulations are performed to explore the feasibility of utilizing nanoparticle and sinusoidal cold inner cylinder to decrease time of solidification. Storage tank is full of NEPCM (CuO-water). The focus of current modeling is on the impacts of shape of cold wall and concentration of NEPCM on discharging rate. Simulation of the transient process was carried out employing FEM based Galerkin method. Decreasing amplitude of inner wall results in prolonging solidification while increasing N, results opposite outcome. Propagation rate of solid fraction enhances with augment of volume fraction of NEPCM.
