PERIODIC TRIPLING AND JET ERUPTION OF FORCED STEEP GRAVITY WAVES
Abstract
Period tripling of standing waves in a circular tank generated by the side-wall excitation is investigated for the first time. With the increasing of forcing acceleration after the appearance of axisymmetric standing wave, period-tripled non-breaking standing waves and violent jet eruption between the modes are observed. However, the physical mechanisms for the generation of the interesting period-tripled standing waves are still unknown and need further research.
