Abstract
Recently, the difference of power consumption during daytime and nighttime becomes a problem from the viewpoint the environmental protection. There is a latent heat storage system for the one of the solution of this problem. In this experiment, phase change microcapsule as a heat storage material was used. The purpose of this study is to investigate the effect of experimental on parameters heat transfer characteristic of latent heat microcapsule slurry in a curved pipe. It was clarified the effect of experimental parameters such as fluid velocity, curvature radius, microcapsule concentration and heat flux.
