The thermal properties of the test O/W-type emulsion were described in the first report. This paper dealts with flow and cold heat-storage characteristics of the oil (tetradecane, C14H30, freezing point 278.9 K) /water emulsion as a latent heat-storage material having a low melting point. A coiled double-tube heat exchanger was used for the cold heat-storage experiment. The pressure drop, the heat-transfer coefficient and the finishing time of cold heat storage in the coiled tube were measured as experimental parameters. It was clarified that the flow behavior of the emulsion as a non-Newtonian fluid played an important role in cold heat storage. The useful nondimensional correlation equations for the additional pressure loss coefficient, the heat-transfer coefficient and the finishing time of the cold heat storage were derived in terms of Dean number and heat capacity ratio.
