Sloshing is a common flow phenomenon in liquid cargo tanks and has great negative impact on the stability safety of ship navigation. It important to understand sloshing process under excitation complex external conditions for transportation cargo. In this paper, characteristics tank are studied combination roll surge. The pressure distribution at different positions discussed, along with influe...

We propose an efficient model for the description of three-dimensional (3-D) evolution breaking water waves in nearshore region. A fundamental property is its intrinsic ability to account 3-D dynamics vorticity and energy dissipation induced by wave breaking. In particular, achieved through use mollified operators, approach similar spirit that adopted smoothed particle hydrodynamics. Further, s...

Water storage tanks not designed explicitly for seismic loading could require retrofit. One of the common ways of retrofit include some structural change in the lateral load resisting system that could be expensive and requires the tank to be out of service for relatively long time. This paper introduces a novel method to reduce seismic demand on tank’s wall without structural intervention. Thi...

We numerically study gravity’s effect on sloshing in a two-dimensional tank which is highly filled by water (95% and 5% air). Both fluids are considered to be incompressible inviscid. The surface tension phase change neglected. OpenFOAM software used for the simulation. A standing wave of impacting lid at its center symmetric wetted region starts advance along lid. simulation carried out (only ...

Oscillating water column wave energy converter is a power generation device in which ocean waves excite the oscillation of surface an air chamber, generates fluctuations pressure and rotate turbine generator(s). The fluid chamber phenomenon with natural period, similar to container such as sloshing. Previous research has shown that for oscillating single submerged water, characteristics can be ...

This paper presents a numerical study of the free-surface evolution for inviscid, incompressible, irrotational, horizontally forced sloshing in a twodimensional rectangular vessel with an inhomogeneous bottom topography. The numerical scheme uses a time-dependent conformal mapping to map the physical fluid domain to a rectangle in the computational domain with a time-dependent aspect ratio Q(t)...

The demand for liquid carriers, such as liquefied natural gas (LNG), has increased in recent years. One of the most common types LNG carriers is membrane type, which often built by a shipyard with prismatic tank shape. This carrier commonly known its effective ways to mitigate sloshing using baffle. Therefore, this study was performed evaluate vertical and T-shape baffles. conducted 25% 50% fil...

free surface sloshing of liquid in a rectangular tank induced by lateral excitation has been studied numericallyand experimentally in this paper. the numerical simulation is carried out based on the volume of fluid (vof) method that provides free surface extraction in such problem. a tank with transparent walls is used to free surface tracking in experimental study while the movement amplitude ...
