Numerical study of free convection effect for directional crystal growth of CdZnTe single-crystals
Computation method of the radiative heattransfer and free convection in the growth ampoule was suggested. It is based on numeric computation of two phase problem with unknown shape of interface. Computation was realized in two steps: on the first step heat transfer problem was solved, in which cryst...

| description | Computation method of the radiative heattransfer and free convection in the growth ampoule was suggested. It is based on numeric computation of two phase problem with unknown shape of interface. Computation was realized in two steps: on the first step heat transfer problem was solved, in which crystal/melt region was considered as one phase region with variable thermo physical properties, on the second step two phase problem was solved, in which thermal problem was solved in solid phase and thermal problem together with free convection problem in melt phase. Computations were carried out in the integrated development environment COMSOL Multiphysics 3.5. |
