Flow-induced sloshing of a free surface in a tank containing water has been observed experimentally. The tank is a rectangle of H0.65m×W0.5m×D0.05m with a horizontal inlet on a narrow side and an outlet at the bottom. Sloshing occurs under the condition of steady inlet flow of a specific flow rate and water depth. This phenomenon is calculated by a numerical analysis method. The method treats the flow as a two-dimensional potential flow with a moving liquid surface. The laplace equation of a velocity potential is solved by the boundary element method. The inlet jet flow and the circulating flow in the container are represented by discrete vortices and are solved by a votex method. The results are compared with those of the experiment.
