Two stratified fluids (water and spindle oil) in aspect ratio of 1 to 1 were studied experimental with the variation of an initial temperature and a cooling surface temperature in square cavity with a lower cooling surface. As an initial temperature and a cooling surface temperature were varied, the supercooling phenomenon was observed. As soon as a supercooling phenomenon was finished, a latent heat was emitted. It was investigated the range of the temperature that the spindle oil was increased with the influence of the latent heat. In case that the initial temperature was low, the temperature of spindle oil was increased up to the upper part of the test section. In other case, the temperature of spindle oil was increased up to the center of that oil.
