Heat Transfer Model for Solidification Process of NH4Cl Solution
In this thesis, a unidirectional solidification model of NH4Cl solution is developed. The dynamics processes of the unidirectional solidification, such as temperature distribution and the location of phase interface are simulated timely. Based on those result data, the heat and mass transfer characteristic is analyzed. And it is found that with the stirring of the liquid zone, the temperature gradient in the liquid zone is decreased from 194 K/m to 24 K/m, and the thickness of the mush zone is enlarged.
