Enhancement of heat transfer was investigated experimentally on a natural convection adjacent to a vertical, heated plate. A V-shaped diverter plate was attached on the surface of the vertical plate and was utilized as a heat transfer promoter. The flow and temperature fields around the diverter plate were visualized to grasp the mechanisms of heat transfer enhancement. The local heat transfer coefficients were also measured using water as a test fluid. The results show that the high-temperature fluid ascending the vertical plate branches at the edge and flows away to both sides of the diverter plate. The low-temperature fluid enters the region behind the diverter plate instead. Thus, the heat transfer coefficients are increased markedly here. The optimum height and inclination angle of the diverter plate were also investigated.
