Resonant frequencies in an elevated spherical container partially filled with water: FEM and measurement

Damage detection in elevated spherical containers partially filled with liquid

“…The mode shape associated to this frequency is the fundamental mode, in which the sphere contains the total coupled mass of liquid with no sloshing, similar to a solid body. More details of the dynamical behaviour of a spherical container including the numerical model are reported in Curadelli et al [29].…”

Parametric study for optimization of storage tanks considering sloshing phenomenon using coupled BEM–FEM

“…Gavrilyuk et al [24] studied linear and nonlinear sloshing in a circular conical tank. Mciver [25], Papaspyrou et al [26], Yue [27] and Curadelli et al [28] modeled sloshing in spherical tanks. Some researchers such as Liu and Lin [29], Panigrahy et al [12], Jung et al [16] and Hasheminejad and Aghabeigi [18] used horizontal and vertical baffles inside the tank with different geometric shapes to prevent sloshing.…”

Numerical simulation of liquid sloshing using arbitrary Lagrangian-Eulerian level set method

“…The growth of the surface wave in a partially filled oscillating tank is known as sloshing, and is important for structural integrity of the tank. 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 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]. Although the method using the body force is easy from the view point of numerical simulation, the method using the moving grid seems apparently to be corresponding to the real phenomena.…”
