On the influence of disjoining pressure on nonlinear oscillations of a water layer on the surface of a charged melting hailstone

The influence of a disjoining pressure on the nonlinear oscillations of a thin charged liquid layer on the surface of a spherical solid core is investigated by means of second-order asymptotic calculations. With the initial deformation governed by a kth mode in the spectrum of modes excited via nonlinear interaction, the disjoining pressure causes the frequencies of modes with numbers smaller than k to decrease and the frequencies of modes with numbers larger than k to increase. In the presence of the disjoining pressure, the amplitudes of all nonlinearly excited modes grow compared with the respective amplitudes without the pressure.
