From the viewpoint of controllability of heat transfer, we investigated heat transfer characteristics on a flat plate facing to a rotating disk with a small gap, and the flow within the gap was directing toward the center of the disk (inward flow). At this configuration, it was expected that the heat transfer on the flat plate was strongly dependent on the friction drove directly by the disk. Some experiments were conducted at various flow rate and various rotation speed of the disk, and the results show superior heat transfer characteristics than that of outward flow case, i.e., the gap flow direct toward outer edge of the disk. The growing flow rate increases the heat transfer all over the heat transfer area under the disk, and the growing rotation speed augments the heat transfer rate near the outer edge of the disk, especially.
