The effects of inner rotating plate with horizontal axis on the heat transfer between vertical two wails in a rectangular enclosure with stratified fluid layers were investigated experimentally. The aspect ratio of the enclosure height/width was 1 throughout the experiments. An acrylic plate with small thermal conductivity was installed horizontally at the center of the square enclosure, and was rotated at various speeds for normal and reverse rotations by using the motor attached outside of the enclosure. Purified water and silicon oil were used for the working fluid and were stratified in the enclosure. It is clarified here that the heat transfer rate of the enclosure with stratified fluid layers differs largely from that of the enclosure with single fluid layer. Namely, the heat transfer rate increases exceedingly at low rotating speed range, and keeps almost constant value at high rotating speed range.
