Water has an anomalous relationship between temperature and density. When water is cooled by two horizontal cooling tubes placed vertically in a rectangular enclosure, both downward and upward convection interfere with each other between the two tubes. The flow pattern of this convection is influenced by the tube separation distance and the cooling rate. We studied the effects of these factors by laser measurement techniques and numerical calculation, and some interesting relations were acquired. The tube separation distance has the great effects on the development of the density inversion flow, the release of supercooling, and the heat transfer characteristics. In this paper, we mainly discuss about these effects of the tube separation distance, and attempt to clear the cooling and freezing behavior of the water in this type cooling system.
