| With the rapid development of global industry, the problem of energy running short has been paid more attention to, and the sense of energy saving has been strengthened gradually, which makes the research on energy storage to be more important. Phase change energy storage system has become a basic mode of energy storage because of its high density of energy storing and some other advantages.Phase change heat transfer of the phase change materials is a strong nonlinear problem, and the heat transfer of solidification and melting has always been focused on domestic and overseas. In this paper, experimental research and simulation of the glycol packed in a beaker are done.By experimental analysis and contrast, the influence rules of influence factors on ice making are obtained, including the temperature of the liquid bath and the concentration of the solution. Meanwhile a bidimensional mathematics model of liquid-solid phase change is constructed according to the experiment conditions, grids with equal interval are built by GAMBIT and the results are calculated by FLUENT6.2.16. Temperature field and phase interface varying with time under different experimental conditions are obtained. Compare with the results obtained from the experiment, isotherm and the rule of phase interface moving obtained from the simulation are almost the same.The result in this paper will make a good foundation for developing and rebuilding the dynamic ice making system.
