Influence of adding nanoparticles on solidification in a heat storage system considering radiation effect

Abstract In this attempt, nanoparticle enhanced PCM is employed to enhance solidification rate. To augment low thermal conductivity of H 2 O, CuO nanoparticles were dispersed in it. Also Brownian motion impact was involved in properties of NEPCM. Graphs are obtained via FEM and displayed the impacts of radiation, length of fin and nanoparticles' size. Outputs display that selecting d p  = 40 nm leads to the fastest discharging. Discharging time reduces with increase of thermal radiation.
