Abstract Sloshing is the violent motion of a resonant fluid in moving tank. When moves and interacts with tank, dynamic pressure from such an interaction can cause large deformations tank walls structure. In this study, 3D numerical simulation was carried out five variations LNG ship model: prismatic, rectangular, tube, spherical, new model filling ratio 25%. Forced oscillation roll f = 1.04 Hz...

the ability to perform rolling contact fatigue (rcf) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. in this paper, a multi-body dynamics (mbd) model is proposed, simulating the vibration behaviour of the prescribed rig. the new testing facility is modelled using a three-dimensional model of the vehicl...

Sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. In recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. On the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...

The severe sloshing induced by earthquake in cylindrical liquefied petroleum gas (LPG) storage tank is of great concern for liquid design. For suppressing sloshing, porous material attached to inner periphery the wall proposed and studied numerically using OpenFOAM. model was validated against with available data without ring baffle, flow through media a U-tube dam break. Fair agreements betwee...

In the past several years, continuous effort has been made in RIAM, Kyushu University to develop an efficient Cartesian grid method for violent free surface problems in ship and ocean engineering. Our researches have been focused on (1) Accurate and robust flow solver for multi-phase flows with solid bodies. (2) Conservative and smearingless interface capturing scheme. In the numerical method, ...

This paper presents ExxonMobil’s evolution of a direct sloshing assessment methodology to resolve several challenging technical issues that are essential for evaluating the integrity of LNG containment systems. Among the most significant developments is the introduction of a probabilistic-based framework that facilitates modeling of the high variability of sloshing impact pressures due to slosh...

Sloshing is an important issue for LNG tanks and in general when partially filled tanks are on-board of a vessel. This resonance phenomenon may be connected with complex motions of the filled liquid that can couple with the ship motions and can represent a danger for the tank strucure and for the stability of the ship. In this context, it is very important to identify the possible scenarios ass...

The transient coupling between the vessel motion and liquid sloshing in multiple tanks is investigated. External disturbance factors (e.g., spring constraint or force field) that might affect the oscillation characters of the coupling system are not involved so that the vessel motion is only excited by the liquid sloshing in tanks. The analytical solution for this coupling problem has been deri...

The present paper introduces the sloshing effects on aeroelastic stability and response of flying wing configurations. Using reduced order model based data provided by computational fluid dynamics data, description slosh is introduced into an integrated modelling that accounts for both rigid elastic behaviour flexible aircraft. fully unsteady aerodynamics, modelled in frequency domain via doubl...
