Numerical Assessment of Gravity for Sloshing in Tank Using OpenFOAM

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 right-half side due geometry impact) with without gravity investigate influence this impact. numerical results validated comparing published data. size region, free-surface elevation pressure distribution has been analyzed. It shown that affecting consequently region. These effects growth as time goes. Pressure also influenced gravity.
