Abstract

The rotation of suspended liquid films induced by electric fields has been reported. The liquid film rotates when there is an electric current passing through the suspended film and simultaneously there is an external electric field which is perpendicular to the electric current. In this study, we propose an explanation of the phenomenon based on the electrical forces actuating on the charges induced on the free surface of an ohmic liquid. We describe the electrical and hydrodynamic equations and solve them numerically by using finite elements. The numerical results are compared with the experiments, and good agreement is found.
