Abstract
Identifying phenomena such as natural convection and forced convection has become indispensable when designing heat exchanger and heat pipe ramp, etc. However there has been barely any basic research on combined convection where forced convection and natural convection coexist using the micro-capsule slurry of latent heat storage. Therefore, this research was carried out to explain the combined convection heat transfer characteristics of latent heat storage micro-capsule slurry in a horizontal duct. As a result, the heat transfer coefficient is high in the upper stream of the duct regardless of the phase change of upper surface heating and it decreases toward the down stream. The heat transfer coefficient with phase change is higher in lower surface heating than that without phase change, and heat transfer coefficient at lower surface heating increases more noticeably than that at upper surface heating.
