Numerical simulation of the horizontal Bridgman growth. Part II: Three-dimensional flow
Authors:S Dupont  J M Marchal  M J Crochet  F T Geyling
Abstract:We study the steady-state three-dimensional flow which occurs in a horizontal crucible of molten metal under the action of a horizontal temperature gradient. The geometry and the boundary conditions are similar to those encountered in the Bridgman growth process of semiconductor crystals. We find that three-dimensional effects can have a dramatic influence upon the flow, which, before the onset of periodic disturbances, differs appreciably from its two-dimensional counterpart. We also investigate the sensitivity of the flow to non-symmetric disturbances.
Keywords:Finite Elements  Transient Flows  Three-dimensional Flows  Natural Convection  Interfaces Oscillatory Flows  Crystal Growth  Semiconductors  Gallium Arsenide
