NUMERICAL COMPUTATION OF LIQUID ENCAPSULATED CZOCHRALSKI BULK FLOW INCOMPARISON WITH FLOW VISUALIZATION

Numerical computations were carried out for liquid encapsulated Czochr alski bulk flow for the modeled fluid of glycerol (model for melt) and silicon oil (model for encapsulated fluid) which were employed for te mperature and flow visualization. Axi-symmetric cylindrical model equa tions were derived and numerically solved for stable cyclic solutions to be consistent with the flow visualization experiments to confirm th e present computational system. Afterward, actual physical properties for GaAs and B2O3 were employed for more realistic numerical simulatio n and oscilllatory convection was found for Gr(m)/Re(m)2 values less t han 10.
