Abstract

This study puts forward an analysis of the influence of liquid sloshing upon oscillating vessels by means of numerical modeling. Rectangular cross-sectional tanks incorporating an open-bore and partitioned setups at 20%, 40%, and 60% fill-volume levels were implemented to establish the torque and static pressure exerted solely by the fluid dynamics upon oscillation within the tanks. Through verification of dam-break dynamics, the sloshing models coupled the explicit volume-of-fluid and non-iterative time-advancement schemes within a computational fluid dynamic solver. Utilising an oscillatory frequency of 1 Hz, the resultant liquid impact reduced within the partitioned setup due to the suppression of wave dynamics.
