In this paper, a numerical model is developed based on coupled boundary element–finite element methods (BEM–FEM) to minimize liquid sloshing pressure in trapezoidal tank with different sidewall angles. Different geometric shapes such as rectangular, cylindrical, elliptical, spherical and circular conical have already been studied for ship storage tanks by other researchers. In this paper, a new arrangement, i.e., trapezoidal containers is suggested for liquid storage tanks. The tank shape is optimized based on sloshing pressures and forces for a range of frequencies and amplitudes of sway motion and tank configuration. Fluid is considered to be incompressible and inviscid. Therefore, Laplace equation and nonlinear free surface boundary conditions are used to model the sloshing phenomenon. The results validated using available data showed that a new arrangement of trapezoidal storage panels has a better efficiency against sloshing phenomenon than the conventional rectangular tanks.

Sway Motion

The purpose of this paper was to investigate the internal liquid sloshing and its effects on the ship motion. A mechanical model of ship motion under sloshing impacts is described. The lateral sloshing forces are included in the model. The nonlinear dynamical system is introduced to describe the sway motion of the ship. The results of the numerical simulation and the effects of the internal sloshing loads are analyzed. The feasibility of the approach is thus verified.
