| Abstract: | Paraffin/water emulsions with different mass fractions were experimentally investigated about their flow and heat transfer performances.Their pressure loss and heat transfer coefficient in heat exchangers were tested.The results show that the emulsions with higher paraffin concentration are good in energy storage with good heat transfer performance.The low concentration emulsion has good flow and heat transfer performances,and its heat transfer performance could be better than the water at phase change temperature. |

| Keywords: | phase change materials paraffin/water emulsion heat transfer energy storage |
