3D unsteady numerical analysis of conjugate heat transport and turbulent/laminar flows in LEC growth of GaAs crystals (Q1434588)

The authors study the interaction between turbulent and laminar flows having an immiscible interface for dimensionless parameters close to LEC GaAs growth. The testing calculations of the authors show that a laminar flow can affect a turbulent flow similar to a solid wall; so, the turbulent kinetic energy tends to vanish at the interface between two liquids. Using the developed three-dimensional conjugate model of heat transport and flows in the near-melt zone including the crystal, the melt, the encapsulant, and the crucibles, the authors investigate in detail the heat and mass transfer during industrial-scale LEC growth of GaAs crystals.
