Abstract
The present experiments have been performed for obtaining the melting heat transfer characteristics of micro-encapsulated solid-liquid phase change material and water mixed slurry flow in a circular tube heated with constant wall heat flux. The phase change material having a low melting point was selected for a domestic cooling system in the present study. The governing parameters were found to be latent heat material concentration,heat,flux,and the slurry velocity. The experimental results revealed that the mean heat transfer coefficient of latent microcapsule slurry was about l.3~l.8 times greater than that of the single phase of water. Moreover the effectiveness of heat transfer coefficient to friction factor had a maximum at latent heat material concentration of 25%.
