Abstract

A PSME model is used to study the base aspect ratio effect on resonant fluid sloshing in a 3D tank. Three different depth classes (shallow water, intermediate depth and finite depth) and three base aspect ratios (very long base, half width base and square base) are considered. Longitudinal and diagonal excitations are applied to all cases. Results show that sloshing in lower depth tank strongly depends on the base aspect ratio. Keywords: PSME method; Nonlinear sloshing waves; Base aspect ratio effect.
