On the basis of the simplified formulation of Hsieh [6] for interfacial stability problems, a general dispersion relation of Kelvin-Helmholtz stability in the presence of mass, heat transfer, porous media, surface tension and magnetic field is obtained to generalize the problems studied in references [7-10]. It is found that magnetic field, heat transfer, surface tension and streaming have a stabilizing effect, while porous media has a destabilizing effect on unstable modes.
