The Numerical Simulation of Liquid Sloshing in Microgravity

Abstract. The subject of study is the influence of sloshing liquid on board spacecraft and satellites. Experiments have been carried out with the mini satellite Sloshsat FLEVO, containing a partially filled water tank, in an orbit around earth. These experiments were supported by a computational model for 3D incompressible free-surface flow, including capillary surface physics and coupled solid...

The numerical simulation of liquid sloshing on board spacecraft

The subject of study is the influence of sloshing liquid on the dynamics of spacecraft. A combined theoretical and experimental approach has been followed. On the one hand, CFD simulations have been carried out to predict the combined liquid/solid body motion. Basically a volume-of-fluid (VOF) approach is followed, however with improvements in the treatment of the free liquid surface: these cov...

Numerical Analysis of Sloshing Problem

Many studies have been reported for the sloshing analysis in liquid containers. One of the major concerns in the marine hydrodynamic field is the accurate prediction of impulsive load on internal structures. During violent sloshing, the sloshing-induced impact load can cause a critical damage on tank structure. Such damage cases have been reported for oil tankers, LNG carriers and bulk carriers...

Numerical simulation of liquid sloshing in a partially filled container with inclusion of compressibility effects

A numerical scheme of study is developed to model compressible two-fluid flows simulating liquid sloshing in a partially filled tank. For a two-fluid system separated by an interface as in the case of sloshing, not only a Mach-uniform scheme is required but also an effective way to eliminate unphysical numerical oscillations near the interface. By introducing a preconditioner, the governing equ...
