Use of Traveling Magnetic Fields to Control Melt ConvectionAn axially traveling magnetic wave induces a meridional basic flow in a molten cylindrical zone. This flow can be beneficial for crystal growth applications. In particular, it can be used to effectively stir the melt in long cylindrical columns. Also, it can beneficially modify the thermal and species concentration fields in the melt and the interface shape of the growing crystal. The basic theory of such an application is developed and preliminary data from a mercury column experiment are also presented.
