Abstract

By numerical simulation of the heat transfer among nanoparticles

microencapsulated phase change material(MPCM) and liquid

the factors such as nanoparticle amount

diameter and thermal conductivity

which affect the MPCM-liquid heat transfer Nusselt number

were analyzed. When MPCM absorbed nanoparticles

the effect of the increase of the MPCM-liquid heat transfer coefficient on the phase change period was also studied numerically

providing a theoretical basis for the mechanism of enhancing the heat transfer with nanoparticle.
