This induced flow will in turn alter the morphology of the solidifying melt/solid interface and eventually influence the quality of the final casting. In the present paper, we investigate this induced flow in the system rotating in a general way while physical conditions vary: different rotating conditions, different thermal and solutal gradients, and the non-Boussinesq effect due to variable viscosity of the melt. Results show that, in brief, the induced flow is driven by the gravity due to inclination while modified by rotation. As each of the following parameters is higher: the effective Taylor number (Te), the thermal Rayleigh number (Rt), the solutal Rayleigh number (Rc), or the Lewis number (Le), the induced flow is of larger velocity. The variable-viscosity effect is more complex, depending on the value of other physical parameters. © 2001 Elsevier Science B.V.
