“…In addition, several techniques, such as smooth particle hydrodynamics [26], particle finite elements [27], and boundary elements [28], have been specifically developed or have been successfully applied to describe free surface flow problems [29]. Hybrid or mixed techniques have been also proposed for two-phase flows, as coupled LS and VOF meth-25 ods [30, 31,32,33] or the particle level set method [34], among others [35,36] Moreover, a relevant task in modeling is the validation of simulations by contrasting their computed results with experiments, such as those reported for the…”

“…Ye et al (2012) investigated ultimate capacity of the containment systems of large LNG carriers using nonlinear finite element method with failure modes under different boundary conditions analyzed in details. Zhao and Chen (2015) used a new coupled Level-Set and Volume-of-Fluid (CLSVOF) method based on the Finite-Analytic Navier-Stokes (FANS) approach for the study of the 3D sloshing flow in partially filled LNG tanks. Luo et al (2016;2017) studied the three-dimensional sloshing in a scaled membranetype LNG tank numerically and experimentally.…”

Fluid dynamics analysis of sloshing pressure distribution in storage vessels of different shapes

A series of numerical simulations were performed to investigate the influences of storage vessels shapes on sloshing dynamics under horizontal excitation by employing the open source code OpenFOAM, which has been extensively validated by experimental data for the sloshing flow problem. The results show that the membrane liquefied natural gas (LNG) tanks are subject to lower impact pressure than the cylindrical, rectangular and spherical tanks with the same volume of liquid and the overall tank dimensions, as the slope at the storage vessels bottom changes the flow direction of the liquid and therefore reduces the impact on the vertical wall. In the cylindrical and spherical tanks, higher impact pressure was found on the wall directly opposite to the excitation direction and the maximum impact point will shift away from the external excitation direction as the wave breaks up violently until a quasi-steady state of the sloshing wave rotating along the side wall is reached. The curved surface of the spherical tank could also help reduce the impact pressure when compared with the cylindrical tank.

“…However, the LNG CCS structure is composed of various composite materials and the primary barrier has complex geometry, so it is very difficult to apply the dynamic modeling method. Moreover, a full-scale test, small-scale tank test, and a wet drop test were performed to analyze the fluid behavior due to the interaction of the wall and wave [5,[14][15][16][17][18][19]. Due to the interaction of the LNG and the wall, the jet flow impact runs up along the wall of CCS [19][20][21] and the acceleration of the jet increases momentarily to 1500 times gravitational acceleration [22].…”

Experimental Investigation of Structural Response of Corrugated Steel Sheet Subjected to Repeated Impact Loading: Performance of LNG Cargo Containment System

The primary barrier in contact with LNG (Liquefied natural gas) cargo is manufactured from stainless steel, and has a corrugated membrane structure due to thermal deformation caused by extreme temperature differences. Because the primary barrier is tailored to be LNG watertight, the structural integrity of the primary barrier must be maintained despite the increase in LNG sloshing load. Among the various types of fluid impacts in a cargo hold, jet flow runs up along the wall of the cargo hold and extreme impact load is exerted on the side of the corrugation of the primary barrier. However, the impact behavior of the primary barrier under the prevailing environment has not been investigated due to the limitation of test methods. Thus, in the present study, the inelastic structural behavior of thin-walled and curved-shaped structures for liquefied natural gas cargo containment systems under repeated impact loading was investigated experimentally. Custom-built structural impact test equipment with large-scale weight drop test facilities was fabricated, and a series of structural impact tests were carried out. The impact energy and the number of repetitions were taken into account in order to investigate the characteristics of the inelastic structural behavior, such as plastic deformation and reaction force time history according to impact energy.
