Abstract: This paper reports the sloshing loads and visual analysis in a prismatic tank under violent sloshing conditions. The volume of fluid (VOF) method is used to perform multi-phase analysis of sloshing phenomena. The prismatic shape is an important parameter to estimate safety against sloshing effects. Horizontal motion is considered for periodic excitation motions. Six cases are used for simulating the sloshing loads. The results show the occurrence of the Bagnold and Wagner type impact pressure loads due to violent sloshing. This study also discusses the variable pressure loads when the upper and lower chamfered shapes are changed. Also, the effects of chamfered shapes and sloshing load distributions in the prismatic tank are visualised in this paper.

Keywords: sloshing; impact pressure loads; visualisation; prismatic tank; horizontal excitation; VOF method; numerical analysis; computational fluid dynamics; CFD.
