摘要：
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.
