To understand the characteristics of the flow, heat and mass transfer in the Ba - Cu - O melt for superconducting material YBa 2 Cu 3 O 2-x ( Y 123) single crystal growth by Czochralski method, this paper presents the numerical simulations of the two-dimension unsteady flow, thermal and Y concentration fields in the Ba - Cu - O melt for Y123 single crystal growth. The results show that the flow is steady at a small temperature difference. As the temperature difference in the radial direction increases, the simulation can predict oscillatory flow.
