Some stationary axisymmetric processes of heat and mass transfer in a melt in the Bridgeman crystallization setup are investigated. The absence of stationary regime due to the instability of the stationary solution obtained was shown for large Prandtle numbers. For finitesimal Prandtle numbers, a numerical analysis was made. The view of the corresponding stationary fluid and heat fields is presented.
