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...

In this paper, the sloshing response of liquid in a two dimensional rigid rectangular tank with rigid baffles is investigated using boundary element technique. A baffle is a supplementary structural element which supplies a kind of passive control on the effects of ground shaking. The complicated liquid domain is divided into two simple sub-domains so that the liquid velocity potential in each ...

Sloshing has many industry applications, namely in offshore engineering, aerospace, ship building, and manufacturing. simulation is essential to better understand the sloshing pattern consequently improve tank design reduce noise levels, stresses on structure, optimize baffle configurations arrangements. Thus, aim of this study determine effects perforated (porous) imperforate (solid) baffles p...

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 waves in moving tanks have been studied numerically, theoretically and experimentally in the past several decades. Most reported studies have been for tanks excited by forcing motion in a limited number of directions and with fixed excitation frequencies throughout the forcing. In the present study, a time-independent finite difference method is used to simulate fluid sloshing in the t...

large capacity cylindrical tanks are used to store a variety of liquids. their satisfactoryperformance during earthquake is crucial for modern facilities. in present paper, the behavior of cylindricalconcrete tanks under harmonic excitation is studied using the finite element method. liquid sloshing, liquidviscosity and wall flexibility are considered and additionally excitation frequency, liqu...

car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. to do so, car body acceleration is determined using a 10 dof simulat...

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 present several simulations carried out using Chrono::FSI and Chrono::Vehicle that highlight the two way coupling between the dynamics of a vehicle and the dynamics of a fluid that is free to move in a tank rigidly attached to the vehicle; i.e., a vehicle sloshing problem. The simulations are carried out in Chrono [1] using a monolithic solution; i.e., there is no co-simulation, the entire s...
