Rayleigh-Taylor instability of the interface between conducting and nonconducting fluids in an alternating magnetic field (Q789958)

In the present paper, the influence of an alternating magnetic field on the Rayleigh-Taylor instability of a conducting fluid has been investigated without restriction on the spatial scale of perturbation. It is shown that a plane polarized high-frequency field effectively stabilizes part of the spectrum of three dimensional perturbations of an interface but does not completely suppress the Rayleigh-Taylor instability mechanism. The instability generated by the self-field has the nature of parametric resonance.
