title: Shear wave instability for electrified falling films.
abstract: The effect of an electric field on the shear wave instability pertaining to a gravity driven conducting liquid film is studied based on the Chebyshev-Tau method. The shear wave appears at very large values of the Reynolds number when the inclination angle is sufficiently small. The presence of an electric field shows peculiar behavior on the critical Reynolds number corresponding to the shear mode. It suppresses shear wave instability through the amplification of the critical Reynolds number and leads to a nontrivial stabilizing effect when inclination angle B≥3'. On the other hand, the reduction of the critical Reynolds number is found if the inclination angle is further lowered in magnitude.
