A Study on Sloshing Behavior for Moss Type LNG Tank Based on SPH Numerical Simulation and Large-Scale Model Experiment

A new concept of the liquefied natural gas (LNG) tank shape has been proposed based on the conventional Moss tank to improve the tank storage efficiency. In this research, a series of model tests are conducted for both new shape and conventional spherical shape tank with imposed regular and irregular sway motion. Corresponding numerical simulation based on smoothed-particle hydrodynamics (SPH) method is carried out and its prediction accuracy is discussed by comparing with the model test results and other numerical simulation based on finite volume method (FVM).
