Abstract : Electrohydrodynamic flow of a simple, isothermal gas without dissipative effects over a wavy wall is investigated by the perturbation method. The unperturbed flow has a uniform velocity and non-uniform distributions of density and electric field which vanish at infinity. For the subsonic flow, the surface pressure the stream lines and the electric-field lines are calculated. For the supersonic flow, the linearized solution diverges at infinity. This seems to be due to the non-uniform density distribution of the undisturbed flow. Numerical solutions of an oscillating-piston problem which is a simplified model for the high supersonic flow, are obtained. Some related problems are also investigated. (Author)
