Excitation of Oscillations in the Melt by Frequency-Modulated TMF Conference Paper uri icon

abstract

  • We consider a magnetohydrodynamic flow in a cylindrical vessel caused by frequency- modulated magnetic field traveling along vertical axis in order to estimate the field impact on the flow parameters. To increase the impact efficiency and intensify transfer processes, we propose to generate non-stationary structures of auto-oscillatory type in the melt against the background of a convective flow, whose parameters are connected with the parameters of the modulated electromagnetic field. The forced convective flow generated in liquid metal contributes to its homogenization and can improve the structure obtained at the melt crystallization.
