Study on the liquid water sloshing in two- and three-dimensional models

Liquid sloshing in tanks has many important applications in a variety of engineering fields. In this study, based on a CFD solver, a numerical model is developed to study the liquid water sloshing in two-and three-dimensional tanks. The VOF method is used to capture the fluid interface. In order to validate the proposed model, a 2-D liquid-water sloshing problem was first solved. The variations of the pressure at the monitor point 100 mm below the initial free surface were recorded. Then the method was applied to a 3-D liquid-water sloshing problem and the sloshing-induced moment was obtained. The numerical results were compared and analyzed with experimental measurements. The results confirm that the present method can be adopted to predict the motion of liquid water and analyze its induced moment on the tank boundary when it has a roll motion.
