Abstract: | The problem of calculation of finite-amplitude waves on the cylindrical surface of an ideal incompressible dielectric liquid
jet in a uniform electrostatic field collinear to the unperturbed jet axis is solved using a second-order asymptotic analytic
procedure in ratio of the wave amplitude to the jet radius. Nonlinear corrections to the jet profile, velocity field potential,
and electrostatic potentials inside and outside the jet are of resonant nature. The degenerate resonant interaction between
the wave determining the initial strain and the waves excited due to nonlinearity of the hydrodynamic equations can take place
for waves with different symmetries (different azimuth numbers). |
