Abstract

The transportation of liquids in partially filled tanks is a critical aspect of various industries. During transit, liquid sloshing can cause significant stability issues. To address these challenges, tank designs incorporate internal structures like baffles. Baffles help mitigate sloshing by disrupting fluid motion, enhancing vehicle stability. This study explores the use of different baffle geometries to control fluid stability during transportation in partially filled tanks. Following on from previous work, this study uses Computational Fluid Dynamics (CFD) simulations focusing on understanding how various baffle designs influence the sloshing behavior of water. As a benchmark validation test, simulation of inviscid free sloshing motion in an accelerated rectangular tank was performed. The frequency spectrum was analyzed and compared with the results predicted by the potential flow models.
