Numerical study on solidification process of encapsulated eutectic salt cold spherical nodules

Establishing physical and mathematic models, simulates the solidification process by FLUENT software. Obtains the temperature fields and phase change interface positions changed with time. Analyses the effects of refrigerant temperature and spherical diameter on solidification time. The results show that the lower refrigerant temperature is, the shorter solidification time is and the more quickly phase change interface position changes, and that solidification time is in direct proportion to the spherical diameter.
