Effect of microencapsulated phase change material absorbing nanoparticles on heat transfer

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.
