Outline of Final Research Achievements

The objective of the present study is to experimentally investigate both the heat transfer characteristics and the flow characteristics of the nanoemulsion. The nanoemulsion is one of the nanofluid including the phase change nano particles. Tetradecane and octadecane are utilized as the phase change material for the nanoemulsion. Experimental investigation is carried out by considering specific parameters and features such as the nanoemulsion flow velocity and so on. The relationships between the flow characteristics and specific parameters of the nanoemulsion are discussed in detail. As a result, an evaluation of the local heat transfer coefficient and the pressure drop indicate that the distribution of the local heat transfer coefficient and flow characteristics is strongly affected by both the tetradecane concentration and the flow velocity of the nanoemulsion. Moreover, the latent heat of fusion and the melting point of the nanoemulsion are investigated by DSC.
