Abstract
The effect of a constant axial magnetic field on the thermosolutocapillary (TSC) convection in the floating liquid zone with an undeformed free surface under microgravity (MG) conditions has been studied. It is established that several stable flow regimes may coexist under such conditions in a certain range of parameters. The boundaries of transitions between various convection regimes under MG conditions with various Hartmann numbers have been determined. It is shown that the constant axial magnetic field suppresses TSC convection, so that the region of uncertainty decreases and shifts toward higher Marangoni numbers. The dependence of the structure and intensity of flow on the floating-zone length to radius ratio has been analyzed.
