The problem of solid-liquid interface morphology which plays an important role in crystal growth is a moving boundary. Whereas coupled with melt convection especially directed with forced convection caused by crystal rotation, moving boundary problem is composed of factors that contain third-party coupling in Cz-Si system. Based on FVM, an iterative solution method is proposed under multi-stream coupled environment through simulation to solid-liquid interface morphology and an analysis method is given to research on crystal rotation impact on interface morphology in this paper. Different from the most simulation results, this paper compared simulation results with the true interface morphology which is obtained by quick lift-off method in practice. By comparing the test, simulation results consistent test well.
