Abstract

With the development of offshore LNG production and offloading,sloshing of LNG in partially filled tanks has become an important research subject for the offshore industry.In this paper SPH(Smoothed Particle Hydrodynamics) method is used for the numerical simulation of large amplitude liquid sloshing in two dimensional liquid tanks.The computed wave surface profile is compared with experimental results,well in agreement.The feasibility of this method to be used to simulate large amplitude liquid sloshing is validated.
