“…In this section, the solution of the linearized vessel-liquid-coupling problem is to be derived. The procedure for the liquid sloshing analysis is similar to that in Zhang (2015a). Firstly, the vessel motion effect is separated from the velocity potential φðx; y; z; tÞ ¼ v 1 ðtÞx þ ϕðx; y; z; tÞ ð 8Þ…”

The transient coupling between the vessel motion and liquid sloshing in multiple tanks is investigated. External disturbance factors (e.g., spring constraint or force field) that might affect the oscillation characters of the coupling system are not involved so that the vessel motion is only excited by the liquid sloshing in tanks. The analytical solution for this coupling problem has been derived based on the potential flow theory, which converts the problem to a linear system of ordinary differential equations. The approach to determine natural frequencies of the coupling system is also given. The vessel with one or more rectangular tanks is considered for cases studies. Effects of factors, such as vessel mass, number of tanks, tank configuration and free-surface deformation on the vessel motion, liquid sloshing, and mechanical-energy components of the system are studied systematically.

“…This design aims to avoid simultaneous occurrence of sloshing resonance in all tanks. 5 Zheng and Zhang established rollover dynamics model of storage tank with elliptical cross sections by three methods. The modified model effectively improves the accuracy of tank car’s roll stability in running.…”

The shape of fuel tank is one of the main factors influencing oil liquid sloshing in fuel tank without baffles. The change of oil liquid sloshing pressure and free oil liquid surface area in fuel tanks of different shapes is the focus of this study. First, the reliability of the simulation method is verified by the test. Second, three different shapes of fuel tanks, which are rectangle, ellipse, and triangle, are proposed, and each shape of fuel tank is improved. A series of simulations are carried out under the same condition. The related history curves of oil liquid sloshing pressure and free oil liquid surface area are obtained, and the pressure contours of oil liquid sloshing and position diagrams of free oil liquid surface are displayed in the process of oil liquid sloshing. Finally, simulation data are compared and analyzed. In three different shapes of fuel tanks, it is found that the pressure of oil liquid sloshing in elliptical fuel tank is the biggest and time-area value of free oil liquid surface area in triangular fuel tank is the smallest. The curved bottom wall of fuel tank is beneficial to reduce the pressure amplitude of oil liquid sloshing and time-area value. All things considered, the heart-shaped fuel tank is optimal for reducing the pressure amplitude of oil liquid sloshing and evaporative emission under the same condition.
