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 ...

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...

Sloshing interaction in ship collisions is studied both experimentally and numerically. The rapid change in ship motions resulting from contact loading in collisions initiates violent sloshing inside partially filled liquid tanks on board. Sloshing affects the collision dynamics and reduces the amount of energy available for structural deformations. An understanding of this interaction phenomen...

This study proposes a new wall boundary condition for the grid-stamping on polygon (G-StoP) model, which enables simpler and more efficient handling of surfaces arbitrarily complex-shaped bodies represented using polygons (or meshes). For example, computer-aided design surface data can be used to analyze flow particle-based fluid-solver moving particle semi-implicit method. coupling simulations...

ALEGRA is a multi-material, arbitrary-Lagrangian-Eulerian (ALE) code for solid dynamics being developed by the Computational Physics Research and Development Department at Sandia +tionat Laboratories. It combines the features of modem Eulerian shock codes, such as CTH, with modem Lagrangian structural analysis codes. With the ALE algorithm, the mesh can be stationary (Eulerian) with the materia...

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...
