摘要

The coupling effect between ship motion and liquid sloshing in a beam sea is investigated, with a focus on the influence of liquid types, namely, water and liquefied natural gas (LNG), on the coupling dynamics. A hybrid numerical model, combining a potential flow model and computational fluid dynamics methods, is employed to simulate these interactions. Numerical validation is performed using experimental data from water sloshing tests. Comparisons between water and LNG reveal that liquid type has minimal effects on the ship’s roll motion response in a beam sea, provided the total liquid masses are the same. Regarding sloshing impact pressure, although differences between LNG and water results are minor, substituting LNG with water in physical experiments is shown to yield reliable results.
