Regarding increasing importance of tank wagons and efficiency in fluids transportation, their usage is increasing every day. Thus paying attention to their designs just as dynamic analysis of wagons during travelling time is vitally important. In this task, sloshing coefficient as prominent parameter in tank wagons designing has been investigated. To ease of efficient design, theses parameters ...

In the present work damping effect of sloshing flows in tanks subjected to vertical harmonic oscillations is modelled through Smoothed Particle Hydrodynamics (SPH) numerical method. The prediction energy dissipation these problems interest, among others, aeronautic field appropriately address sloshing-induced loads on aircraft wings. To this purpose, an enhanced SPH scheme applied and extensive...

This paper introduces the experimental results of sloshing model tests carried out at Seoul National University. Two 1/50-scale tanks, i.e., 2D and 3D models with the same shape, were manufactured for the comparative study. Particular interest was taken in the differences in impact pressures between the 2D and 3D models. Regular motion tests were conducted for different filling depths. For each...

It is difficult to evaluate the sloshing load acting on a fixed roof of tank because it depends on the collision of the liquid to the roof. In this paper, the SPH simulation was introduced to evaluate the load acting on a fixed roof. The results obtained by the simulation showed good agreement with those obtained from other method. In addition, the effect of the roof-liquid clearance on the slo...

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...

A mathematical model is developed for calculating liquid sloshing effects such as hydrodynamic pressures and forces in half-full spherical containers under arbitrary external excitation. The velocity potential is expressed in a series form, where each term is the product of a time function and the associated spatial function. Because of the spherical configuration, the problem is not separable ...
