The calculation of the asymptotic analysis of the nonlinear second order shows that the motion of a charged jet relative to the material environment leads to the increase in the time-periodic wave motion of the interface with the environment (Kelvin-Helmholtz instability) and the appearance of a nonlinear internal wave resonant interaction. The parameters of the latter (intensity and the characteristic time of interaction) depend on the physical parameters of the system: the electric charge density on the jet, its velocity relative to the medium, the mass density, wave numbers of the interacting waves, the coefficient of the surface tension of the interface.
Keywords: a moving jet, a nonlinear waves, a surface charge, a material medium, a velocity field tangential discontinuity.
