| 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,VOF (volume of fluid) method is used for the numerical simulation of sloshing in partially filled liquid tanks. With the dynamic meshes,2D rectangular tank and 3D cubic tank and membrane tank are calculated. And the calculated results including transverse force and wave elevation and pressure curves, are compared with experimental results, well in agreement. The feasibility and validity of this method is validated. |
