Abstract


Along with the world energy crisis turning deeply, the ice storage system is applied more and more widely because of its simple design and obviously economy. Especially under the extreme nervous situation of the electric power in our country , the ice storage system has the special and important function of alleviating the nervous situation of the current electric power, and also has the aggressive meaning to the scientific development of the economy of our country.Among all the ice storage systems, internal-melt ice-on-tube has been widely used because of its high reliability and relatively high charging and discharging rate. Therefore, it is important to investigate the mechanism of freezing and meting about ice-on-tube. For this purpose a research of the performance of heat transfer of internal-melt ice-on-tube is carried out theoretically.Through enthalpy method, a three-dimension heat transfer mathematical model for the ice-on-tube with freezing is established. Based on the model the influences of the velocity in the tube, the inlet temperature of flow, the diameter of tube and the initial temperature of the water on the heat transfer characteristics of freezing are analyzed. It provides theoretical instruction of designing ice-on-tube.Besides, under the two circumstances with nature convection and without nature convection, a three-dimension heat transfer mathematical model for the ice-on-tube with melting is established. Based on the model the influences of the velocity in the tube, the inlet temperature of flow, the diameter of tube and the initial temperature of the ice on the natural convection of the melted water and the heat transfer characteristics of melting are analyzed. It provides theoretical instruction of optimizing system and matching parameters.
