NUMERICAL SIMULATION OF SLOSHING DYNAMICS IN A TANK
Abstract
The present work describes a study which describes the effect of sloshing liquid in the LNG tanks. More simulations have been made by a CFD codewhich is based on Navier-Stokes equations and uses two phase flow effects. These phenomena are important for sloshing in the tanks and the complex mixture of the liquid and gas phase around the free surface involves a challenge to numerical simulation. Moreover, the two phase flow is strongly affected by both the filling amount of the tank and the irregular motion of the tank due the offshore conditions.
Numerical results are presented from large scale of an LNG carrier filled 10% with liquid and compressible gas, which shows both fluid height and fluid pressure exerted on tank walls. This paper presents only part of the analyzed results, respectively, four pressure points and three water height probes, a regular sway motion being considered.
