Abstract
The effect of the height of a melted layer on its thermal structure is examined. The maximum velocities of ascending and descending flows during crystal growth by the Stockbarger method with the use of the accelerated crucible rotation technique in crucibles100 mm in diameter at Taylor numbersTa>10 8 are estimated. A sudden increase in the amplitude of temperature oscillations with diminution of the height of the melted layer caused by unsteady rotation of the crucible is found. With decreasing height of the melted layer, the velocity of both ascending and descending flows at the axis of a cylindrical ampoule decreases.
