The characteristics of natural convective heat transfer on a vertical heated plate with a single square solid element was numerically and experimentally examined. Experiment was optically performed by using Mach-Zehnder interferometer. A solid element tends to make the thermal boundary layer increase. As the results, the local heat transfer is depressed, and from the reattachment point it is improved along the wake of a solid element. When a space exists between the heated plate and a solid element, the flow is accelerated and the local heat transfer is remarkably improved. The effect of thermal conductivity of a solid element is also examined. These results give us basic data on a location of a solid element in a room with air-conditioning system.
