Abstract: | Numerical modeling of the temperature distribution, the velocity fields, and the dopant (Ge:Si) concentration during germanium
crystal growth by the floating zone method under microgravity is carried out. The time-dependent three-dimensional problem
is solved using the difference method. The deformations of the free surface of a liquid bridge and of crystallization and
melting fronts are neglected. The relaxation of axisymmetric flow regimes to a steady state is observed, whereas the unsteadiness
of three-dimensional flows develops with time. |
