A numerical study was performed on the fluid flow in the melt of the cold model for Czochralski growth system. The fluid flow in the Woods metal with crucible radius of 20cm was calculated using a three dimensional finite difference method. Since the crucible size is large, fully turbulent model as well as laminar model was used in the calculation. The effects of crucible rotation rate, crystal rotation rate and wall temperature on the velocity and temperature distribution was also investigated. For the purpose of verifying the results of calculation, a cold model experiment using. Woods metal was also conducted and the velocity distribution in the melt of the model was measured.
