| The excitation of wave motion by an external source and the interaction of modes inherent to a flow in a dispersive medium are considered. Dispersion is caused by the presence of gaseous bubbles in a liquid. A large variety of steady excited waveforms is possible when the exciting wave is also steady and propagates at a constant velocity. The velocities of the exciter and forced waves may be different. This leads to a variety of non-stationary excitations. |
