Effect of rotation and a magnetic field on Rayleigh Taylor stability

Abstract

In this paper the hydromagnetic stability of an incompressible fluid of variable density in the presence of magnetic field as well as rotation is considered. The magnetic field is taken along axis of rotation and stratified in the direction. A variational principle for the problem under consideration has been established. Two density configurations viz. (i) density varies continuously with height and (ii) two superposed fluids of great depths have been studied in detail.
