Abstract

An emulsion dispersed nano-size particles of phase change material is produced. We discuss with the thermophysical properties, the stability of emulsion, and the heat transport characteristics as a thermal functional fluid. The testing emulsion, which has nano-size particles as the discrete phase, is produced with a D-phase emulsification method. The diameter of discrete phase in the emulsion is measured for evaluation of the long- Term stability of emulsion. In addition, the DSC curve of emulsion is determined. The results reveal that the emulsion with the D-phase emulsification method has the superior stability. From the differential thermal analysis, the DSC curve of present emulsion indicates a discontinuous change at the phase change temperature of phase change material due to its latent heat.
