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...

Liquid sloshing is a common phenomenon in the transporting of liquid tanks. Liquid waves lead to fluctuating forces on the tank wall. If these fluctuations are not predicted or controlled, they can lead to large forces and momentum. Baffles can control liquid sloshing fluctuations. One numerical method, widely used to model the liquid sloshing phenomena is Smoothed Particle Hydrodynamics (SPH)....

This study investigates the effect of nonlinear strengths sloshing on damping performance side-mounted perforated baffles and discusses influence resonance characteristics flow. The model score is adopted to evaluate strength water sloshing. A microscopic a volume-averaged macroscopic are established simulate flow in two-dimensional (2D) tank with baffles. In addition, series experimental tests...

A spherical pendulum-type model was constructed to represent liquid sloshing in a cylindrical container caused by container transfer along a curved path. The model was used to design a curved path and a transfer control system in consideration of the damping of sloshing in the container. The curvature radius of the curved path and the acceleration of the container were determined using an input...

Soil-structure interaction (SSI) could affect the seismic response of structures. Since liquid storage tanks are vital structures and must continue their operation under severe earthquakes, their seismic behavior should be studied. Accordingly, the seismic response of two types of steel liquid storage tanks (namely, broad and slender, with aspect ratios of height to radius equal to 0.6 and 1.85...

The present study is to carry out a numerical sloshing using smoothed particle hydrodynamics (SPH) in the prismatic tank. Sloshing violent flow caused by resonance of fluid tank external oscillation. was used resemble membrane LNG type carrier. experiment carried three pressure sensors, camera high resolution, and four degrees freedom forced oscillation machine. In this study, filling ratio 25%...

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...

Clearance of Thrust Vector Control (TVC) laws for launchers demands the capability to provide analytical certificates for the system’s robust stability. During exo-atmospheric flight, a key role is played by the ability to deal with non rigid-body effects such as fuel sloshing. Depending on its frequency and magnitude, sloshing can easily deteriorate the performance of the TVC laws to the point...

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...
