Abstract
In this study, the sloshing characteristics in a circular tank on an oscillation table are investigated. Firstly, laboratory experiments were conducted under the various hydraulic conditions, and the characteristics of water surface oscillation were examined. To simulate the flow fields in experiments, a shallow water equation in generalized curvilinear moving coordinate system was used, in which a pressure distribution was assumed to be hydrostatic, and linear and nonlinear solutions were derived. In addition, a Boussinesq equation is also applied. The sloshing characteristics obtained from the theoretical and numerical solutions were verified by comparing with the experimental results.
