Abstract
Two numerical models, a CIP (Constrained Interpolation Profile) based method and a MPS (Moving Particle Semi-implicit) method, were used to study violent sloshing flow inside the tanks of membrane-type LNG carriers. A comparison study by the two methods on a two-dimensional experimental problem was performed. The CIP-based Cartesian grid method was robust for violent free surface motions. The interface-capturing scheme used in the code worked efficiently with perfect mass conservation and non-diffused free surface. The pressure on the tank wall could be predicted well. The present MPS method was very promising. A good prediction could be obtained by using quite limited number of particles. Treatment of inner structures and complex wall geometries was simple, which made the MPS method very applicable for studying practical LNG tanks. This is an abstract of a paper presented at the Nineteenth (2009) International Offshore and Polar Engineering Conference Proceedings (Osaka, Japan 6/21-26/2009).
