Abstract
This paper dealt with physical properties of the oil (tetradecane, C14H30, melting point of 278.9K) water-emulsion as a latent heat storage material having a low melting point. The measured results on physical properties of the test emulsion, i.e., density and viscosity, were discussed in the temperature region of solid and liquid phases of the dispersion material (tetradecane). It was clarified that the emulsion density could be estimated by mixing ratio of the emulsion constituents. The useful correlation equations of the viscosity for the emulsion were proposed in terms of temperature and concentration ratio of the emulsion constituents.
