Abstract
The surface instability of KelvinHelmholtz type bounded above by a porous layer and below by a rigid surface is investigated using linear stability analysis. Here we adopt the theory based on electrohydrodynamic as well as Stokes and lubrication approximations. We replace the effect of boundary layer with Beavers and Joseph slip condition. Here we have studied the effect of electric field on KHI in a fluid layer bounded above by a porous layer and below by a rigid surface. The dispersion relation is obtained through normal mode technique using suitable boundary and surface conditions and results are depicted graphically. From this it is clear that the effect of electric field with porous layer is more effective than the effect of compressibility in reducing the growth rate of RTI. Also, these results shows that with a proper choice of electric parameter it is possible to control the growth rate of EKHI and also it is found that the electric field stabilizes the system.
