dc.description.abstract Everyone knows that water is the most important thing to make our living. However in Korea, many expert organizations have predicted that it will also become water deficiency in the near future. As becoming generally known, the most effective method is to desalinize the sea water in order to obtain the fresh water. In this present, there are various methods for the desalination of sea water. But the most considerable point for adopting the desalination system is the production cost of fresh-water based on an energy source which should be obtained easily and cheaply. Recently in Korea, the demand of Liquified Natural Gas (LNG), as a cheap and clean energy which does not cause an environmental problem, is greatly being increased. In general, we put this LNG in storage as a liquid state at below -162℃ in a tank. When the LNG transforms to the gaseous state at high pressure, it absorbs energy from a heat source. In this process, a large amount of cold energy is wasted. Therefore, we focused to make the desalination system by utilizing this wasted cold energy. In characteristic point of sea water, high concentration of aqueous solution becomes an eduction from frozen surface in case it frozen over. Therefore, it is possible to desalinize from sea water. First of all, we have to reveal the freezing mechanism of sea water so as to make the desalination system. The goal of this study is to measure the freezing quantity and freezing rate, and to investigate the freezing heat-transfer characteristics in a Circular Tube. The experimental results will help to provide a general understanding of the sea water freezing behavior to reach completion of the desalination system in the future. -
