Abstract

A self-induced sloshing caused by an upward plane jet was recently discovered in a rectangular test tank. The submerged jet entered the tank from an inlet at the bottom center and impinged vertically on a free surface. Under a certain water depth and inlet velocity condition, the first mode sloshing was observed. At the sloshing, the visualized jet streakline had a peculiar oscillatory behavior. Based on the observation, a relation-between the sloshing period and a time was noticed, which was required for the jet fluctuation to travel from the inlet to the surface. As a result, the sloshing was found to occur when the traveling time of the jet fluctuation was about discrete constant times as long as the sloshing period.
