Abstract: (1727 Views)
In this study, the effect of magnetic field on the instability of the interface between two semi-infinite fluids of constant density is investigated as well as two semi-infinite fluids of variable density. A general equation for the amplitude of disturbance near the interface is obtained using the MHD equations. The results show that temporal part of the disturbance amplitude for both cases is the same. in the other hand The spatial part of the perturbation amplitude of the fluids with constant densities decreases exponentially while in the case of varying densities it descents faster because of a hypergeometric function in the solution.
