Abstract
<p>This study deals with an experimental investigation of heat transfer characteristics of nanosuspension as a heat medium. Nanosuspension is a fluid that uses nano-sized latent heat storage material having a melting point temperature higher than normal temperature as a dispersoid. Tetracosane (melting point 50.6 °C) is selected for the dispersoid as a latent heat storage material. A non-ion surfactant polioxyethylencetylether is used for the dispersion stability of the dispersoid in the distilled water that is a dispersion medium. The dispersoid composition ratio of the nanosuspension is measured in the range of 10 to 20 mass%. This paper shows the results on the condition that nanosuspension with nonNewtonian flows in a straight circular tube. The heat transfer coefficient was measured and evaluated in each temperature range of the liquid phase of dispersoid (>melting point) and the solid phase of dipersoid (<melting point).</p>
