| Abstract: | A bushing heat storage model with phase change material, lauric acid, is established. By developing the mathematical model of the melting process, the dynamic characteristic of the vessel is obtained. Dynamic development of temperature, liquid fraction, density of thermal flux of PCM with different radius are simulated and discussed. The regular pattern of density of thermal flux between refrigerant and PCM is also got. |
