“…Sloshing has been studied experimentally and numerically, for instance in relation to sea transport of oil and liquefied natural gas [7,8], seismic response of liquefied petroleum gas tank in petrochemical industry [9], and so on. The effect of oscillating tank on fluid motion was, in some cases, taken into account by including a body force induced by the tank motion in the momentum equation of fluid [7,8], as was the case for nuclear reactors [1,2,4,6]. The computational grid for fluid simulation was, in other cases, moved directory according to the tank motion [9].…”
