Abstract: | An analytic expression for the electrostatic field strength at the free surface of a thin layer of a uniformly charged viscous
incompressible liquid is obtained in second-order asymptotic calculations in the amplitude of a periodic capillary-gravity
wave propagating over the liquid surface. It is shown that a corona discharge at the crests of the waves can be initiated
at subcritical values of the field strength (in the sense of possible realization of the Tonks-Frenkel instability). The electrostatic
field strength at the crests of nonlinear waves increases with the wavenumber and the wave amplitude. |
