A jet under a free surface can induce sloshing in a tank without an oscillating external force. In the previous study, the authors proposed a new growth model of self-induced sloshing caused by a vertical plane jet. The model was based on a feedback loop which simply simulated the interaction between the jet and the free surface. The dependence of sloshing on the tank geometry, water depth and inlet velocity was qualitatively evaluated. In this study, the model was applied to self-induced sloshing caused by a horizontal rectangular jet. Under a certain geometric condition of a rectangular tank, 1st and 2nd mode sloshings were observed The growth of multimode sloshing was qualitatively explained by the model. The self-induced sloshing was considered to be excited by a jet-surface interaction regardless of the incident jet angle to the surface.
