Fast waves development initiated by oscillations of a recoiling liquid filament in a viscous fluid jet

The work describes regularities of the formation of waves in a jet of a viscous liquid, initiated by a sudden rupture of the jet. The possibility of the existence of fast growing disturbances in a viscous jet is established. The cyclic regularity of the dependence of the distance between the formed droplets on their number is observed. It is justified that he decisive role in the formation of growing fast waves is played by effects caused by the action of the force of viscous friction.
