| Abstract: | Numerical modeling of temperature distribution, velocity and dopant concentration in crystal growth by the floating zone method
in microgravity conditions is carried out taking into account thermocapillary and solutocapillary effects. The deformations
of free surface and the curvature of crystallization and melting fronts are neglected. Non-stationary three-dimensional problem
is solved by finite differences method. The establishing of stationary axisymmetrical regimes as well as the development of
non-stationary three-dimensional regimes are observed. |
