摘要：
Computer simulation was conducted to study heat transfer and fluid flow in normal gravity floating-zone crystal growth of NaNO3 with: (1) fast feed/crystal counterrotation and (2) fast single rotation of the feed or crystal. Natural convection, thermocapillary convection and forced convection were considered. The shapes of the melt/gas, melt/crystal and melt/feed interfaces were calculated and compared with those observed during crystal growth. The effects of key operating parameters were discussed, including the mode and speed of rotation, growth rate, heat input and growth direction.
